4 Frame structure and physical resources #
4.1 General #
Throughout this specification, unless otherwise noted, the size of various fields in the time domain is expressed in time units \(T_c = \frac{1}{\Delta f_{\max} \cdot N_f}\) where \(\Delta f_{\max} = 480 \bullet 10^{3}\) Hz and \(N_f = 4096\). The constant \(\kappa = T_s/T_c = 64\) where \(T_s=\frac{1}{\Delta f_{\mathrm{ref}}\cdot N_{f,\mathrm{ref}}}\), \(\Delta f_{\mathrm{ref}} = 15 \cdot 10^{3}\ \mathrm{Hz}\) and \(N_{f,\mathrm{ref}} = 2048\).
Throughout this specification, unless otherwise noted, statements using the term "UE" in clauses 4, 5, 6, or 7 are equally applicable to the IAB-MT part of an IAB-node and the NCR-MT part of an NCR node.
4.2 Numerologies #
Multiple OFDM numerologies are supported as given by Table 4.2-1 where \(\mu\) and the cyclic prefix for a downlink or uplink bandwidth part are obtained from the higher-layer parameters subcarrierSpacing and cyclicPrefix, respectively.
Table 4.2-1: Supported transmission numerologies.
\(\mu\) | \(\Delta f = 2^{\mu} \cdot 15\,[\mathrm{kHz}]\) | Cyclic prefix |
0 | 15 | Normal |
1 | 30 | Normal |
2 | 60 | Normal, Extended |
3 | 120 | Normal |
4 | 240 | Normal |
5 | 480 | Normal |
6 | 960 | Normal |
4.3 Frame structure #
4.3 .1 Frames and subframes #
Downlink, uplink, and sidelink transmissions are organized into frames with \(T_f = \left(\frac{\Delta f_{\max} N_f}{100}\right)\cdot T_c = 10\,\mathrm{ms}\) duration, each consisting of ten subframes of \(T_{sf} = \left( \Delta f_{\max} N_f / 1000 \right) \cdot T_c = 1\,\mathrm{ms}\) duration. The number of consecutive OFDM symbols per subframe is \(N_{\text{symb}}^{\text{subframe},\mu} = N_{\text{symb}}^{\text{slot}}N_{\text{slot}}^{\text{subframe},\mu}\). Each frame is divided into two equally-sized half-frames of five subframes each with half-frame 0 consisting of subframes 0 – 4 and half-frame 1 consisting of subframes 5 – 9.
There is one set of frames in the uplink and one set of frames in the downlink on a carrier.
Uplink frame number \(i\) for transmission from the UE shall start \(T_{\text{TA}} = \left( {N_{\text{TA}} + N_{\text{TA,offset}} + N_{\text{TA,adj}}^{\text{common}} + N_{\text{TA,adj}}^{\text{UE}}} \right)T_{\text{c}}\) before the start of the corresponding downlink frame at the UE where
- \(N_{\text{TA}}\) and \(N_{\text{TA,offset}}\) are given by clause 4.2 of [5, TS 38.213], except for msgA transmission on PUSCH where \(N_{\text{TA}} = 0\) shall be used;
- \(N_{\text{TA,adj}}^{\text{common}}\) given by clause 4.2 of [5, TS 38.213] is derived from the higher-layer parameters ta-Common, ta-CommonDrift, and ta-CommonDriftVariant if configured, otherwise \(N_{\text{TA,adj}}^{\text{common}} = 0\);
- \(N_{\text{TA,adj}}^{\text{UE}}\) given by clause 4.2 of [5, TS 38.213] is computed by the UE based on UE position and serving-satellite-ephemeris-related higher-layers parameters if configured, or is computed by the UE based on UE position and gNB location provided by atg-gNB-Location if configured, otherwise \(N_{\text{TA,adj}}^{\text{UE}} = 0\).

4.3 .2 Slots #
For subcarrier spacing configuration \(\mu\), slots are numbered \(n_{\text{s}}^{\mu} \in \left\{ {0,\ldots,N_{\text{slot}}^{\text{subframe},\mu} - 1} \right\}\) in increasing order within a subframe and \(n_{\text{s,f}}^{\mu} \in \left\{ {0,\ldots,N_{\text{slot}}^{\text{frame},\mu} - 1} \right\}\) in increasing order within a frame. There are \(N^{\text{slot}}_{\text{symb}}\) consecutive OFDM symbols in a slot where \(N^{\text{slot}}_{\text{symb}}\) depends on the cyclic prefix as given by Tables 4.3.2-1 and 4.3.2-2. The start of slot \(n_{\text{s}}^{\mu}\) in a subframe is aligned in time with the start of OFDM symbol \(n_{s}^{\mu} N_{\text{symb}}^{\text{slot}}\) in the same subframe.
OFDM symbols in a slot in a downlink or uplink frame can be classified as 'downlink', 'flexible', or 'uplink'. Signaling of slot formats is described in clause 11.1 of [5, TS 38.213].
In a slot in a downlink frame, the UE shall assume that downlink transmissions only occur in 'downlink' or 'flexible' symbols.
In a slot in an uplink frame, the UE shall only transmit in 'uplink' or 'flexible' symbols.
A UE not capable of full-duplex communication and not supporting simultaneous transmission and reception as defined by parameter simultaneousRxTxInterBandENDC, simultaneousRxTxInterBandCA or simultaneousRxTxSUL [10, TS 38.306] among all cells within a group of cells is not expected to transmit in the uplink in one cell within the group of cells earlier than \(N_{\text{Rx-Tx}}T_{\text{c}}\) after the end of the last received downlink symbol in the same or different cell within the group of cells where \(N_{\text{Rx-Tx}}\) is given by Table 4.3.2-3.

4.4 Physical resources #
4.4 .1 Antenna ports #
An antenna port is defined such that the channel over which a symbol on the antenna port is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed.
Two antenna ports are said to be quasi co-located if the large-scale properties of the channel over which a symbol on one antenna port is conveyed can be inferred from the channel over which a symbol on the other antenna port is conveyed. The large-scale properties include one or more of delay spread, Doppler spread, Doppler shift, average gain, average delay, and spatial Rx parameters.
4.4 .2 Resource grid #
For each numerology and carrier, a resource grid of \(N_{grid,x}^{size,\mu}\, N_{sc}^{RB}\) subcarriers and \(N_{\text{symb}}^{\text{subframe},\mu}\) OFDM symbols is defined, starting at common resource block \(N^{\text{start},\mu}_{\text{grid}}\) indicated by higher-layer signalling. There is one set of resource grids per transmission direction (uplink, downlink, or sidelink) with the subscript\(x\) set to DL, UL, and SL for downlink, uplink, and sidelink, respectively. When there is no risk for confusion, the subscript \(x\) may be dropped. There is one resource grid for a given antenna port \(p\), subcarrier spacing configuration \(\mu\), and transmission direction (downlink, uplink, or sidelink).
For uplink and downlink, the carrier bandwidth \(N_{\text{grid}}^{\text{size},\mu}\) for subcarrier spacing configuration \(\mu\) is given by the higher-layer parameter carrierBandwidth in the SCS-SpecificCarrier IE. The starting position \(N_{\text{grid}}^{\text{start},\mu}\) for subcarrier spacing configuration \(\mu\) is given by the higher-layer parameter offsetToCarrier in the SCS-SpecificCarrier IE.
The frequency location of a subcarrier refers to the center frequency of that subcarrier.
For the downlink, the higher-layer parameter txDirectCurrentLocation in the SCS-SpecificCarrier IE indicates the location of the transmitter DC subcarrier in the downlink for each of the numerologies configured in the downlink. Values in the range 0 – 3299 represent the number of the DC subcarrier and the value 3300 indicates that the DC subcarrier is located outside the resource grid.
For the uplink, the higher-layer parameter txDirectCurrentLocation in the UplinkTxDirectCurrentBWP IE indicates the location of the transmitter DC subcarrier in the uplink for each of the configured bandwidth parts, including whether the DC subcarrier location is offset by 7.5 kHz relative to the center of the indicated subcarrier or not. Values in the range 0 – 3299 represent the number of the DC subcarrier, the value 3300 indicates that the DC subcarrier is located outside the resource grid, and the value 3301 indicates that the position of the DC subcarrier in the uplink is undetermined.
4.4 .3 Resource elements #
Each element in the resource grid for antenna port \(p\) and subcarrier spacing configuration \(\mu\) is called a resource element and is uniquely identified by \((k,l)_{p,\mu}\) where \(k\) is the index in the frequency domain and \(\ell\) refers to the symbol position in the time domain relative to some reference point. Resource element \((k,l)_{p,\mu}\) corresponds to a physical resource and the complex value \(a_{k,l}^{(p,\mu)}\). When there is no risk for confusion, or no particular antenna port or subcarrier spacing is specified, the indices \(p\) and \(\mu\) may be dropped, resulting in \(a_{k,l}^{(p)}\) or \(a_{k,l}\).
4.4 .4 Resource blocks #
4.4.4.1 General #
A resource block is defined as \(N_{\text{sc}}^{\text{RB}} = 12\) consecutive subcarriers in the frequency domain.
4.4.4.2 Point A #
Point A serves as a common reference point for resource block grids and is obtained from:
- offsetToPointA for a PCell downlink where offsetToPointA represents the frequency offset between point A and the lowest subcarrier of the lowest resource block, which overlaps with the SS/PBCH block, or the SS/PBCH block after puncturing if applicable, used by the UE for initial cell selection, expressed in units of resource blocks assuming 15 kHz subcarrier spacing for FR1 and 60 kHz subcarrier spacing for FR2 and FR2-NTN;
- for operation without shared spectrum channel access in FR1, FR2-1 and FR2-NTN, the lowest resource block has the subcarrier spacing provided by the higher layer parameter subCarrierSpacingCommon;
- for operation with shared spectrum channel access in FR1 or FR2, and for operation without shared spectrum channel access in FR2-2, the lowest resource block has the subcarrier spacing same as the SS/PBCH block used by the UE for initial cell selection;
- absoluteFrequencyPointA for all other cases where absoluteFrequencyPointA represents the frequency-location of point A expressed as in ARFCN.
4.4.4. 3 Common resource blocks #
Common resource blocks are numbered from 0 and upwards in the frequency domain for subcarrier spacing configuration \(\mu\). The center of subcarrier 0 of common resource block 0 for subcarrier spacing configuration \(\mu\) coincides with 'point A'.
The relation between the common resource block number \(n_{\text{CRB}}^{\mu}\) in the frequency domain and resource elements \((k,l)\) for subcarrier spacing configuration \(\mu\) is given by
\(n_{\mathrm{CRB}}^{\mu} = \left\lfloor \frac{k}{N_{sc}^{\mathrm{RB}}} \right\rfloor\)
where \(k\) is defined relative to point A such that \(k = 0\) corresponds to the subcarrier centered around point A.
4.4.4. 4 Physical resource blocks #
Physical resource blocks for subcarrier spacing configuration \(\mu\) are defined within a bandwidth part and numbered from 0 to \(N_{\text{BWP},i}^{\text{size,μ}} - 1\) where \(i\) is the number of the bandwidth part. The relation between the physical resource block \(n_{\text{PRB}}^{\mu}\) in bandwidth part \(i\) and the common resource block \(n_{\text{CRB}}^{\mu}\) is given by
where \(N_{\text{BWP},i}^{\text{start,}\mu}\) is the common resource block where bandwidth part \(i\) starts relative to common resource block 0. When there is no risk for confusion the index \(\mu\) may be dropped.
4.4.4. 5 Virtual resource blocks #
Virtual resource blocks are defined within a bandwidth part and numbered from 0 to \(N_{\text{BWP},i}^{\text{size}} - 1\) where \(i\) is the number of the bandwidth part.
4.4.4.6 Interlaced resource blocks #
Multiple interlaces of resource blocks are defined where interlace \(m \in \left\{ {0,1,\ldots,M - 1} \right\}\) consists of common resource blocks \(\left\{ {m,M + m,2M + m,3M + m,\ldots} \right\}\), with \(M\) being the number of interlaces given by Table 4.4.4.6-1. The relation between the interlaced resource block \(n_{\text{IRB},m}^{\mu} \in \left\{ {0,1,\ldots} \right\}\) in bandwidth part \(i\) and interlace \(m\) and the common resource block \(n_{\text{CRB}}^{\mu}\) is given by
where \(N_{\text{BWP},i}^{\text{start,}\mu}\) is the common resource block where bandwidth part starts relative to common resource block 0. When there is no risk for confusion the index \(\mu\) may be dropped.
The UE expects that the number of common resource blocks in an interlace contained within bandwidth part \(i\) is no less than 10.
Table 4.4.4.6-1: The number of resource block interlaces.
\[\mathbf{\mu}\] | \[\mathbf{M}\] |
0 | 10 |
1 | 5 |
4.4 .5 Bandwidth part #
A bandwidth part is a subset of contiguous common resource blocks defined in clause 4.4.4.3 for a given numerology \(\mu_i\) in bandwidth part \(i\) on a given carrier. The starting position \(N_{\text{BWP},i}^{\text{start,}\mu}\) and the number of resource blocks \(N_{\text{BWP},i}^{\text{size,}\mu}\) in a bandwidth part shall fulfil \(N_{\text{grid},x}^{\text{start},\mu} \leq N_{\text{BWP},i}^{\text{start},\mu} < N_{\text{grid},x}^{\text{start},\mu} + N_{\text{grid},x}^{\text{size},\mu}\) and \(N_{\text{grid},x}^{\text{start},\mu} < N_{\text{BWP},i}^{\text{start},\mu} + N_{\text{BWP},i}^{\text{size},\mu} \leq N_{\text{grid},x}^{\text{start},\mu} + N_{\text{grid},x}^{\text{size},\mu}\), respectively. Configuration of a bandwidth part is described in clause 12 of [5, TS 38.213].
A UE can be configured with up to four bandwidth parts in the downlink with a single downlink bandwidth part being active at a given time. The UE is not expected to receive PDSCH, PDCCH, or CSI-RS (except for RRM) outside an active bandwidth part.
A UE can be configured with up to four bandwidth parts in the uplink with a single uplink bandwidth part being active at a given time. If a UE is configured with a supplementary uplink, the UE can in addition be configured with up to four bandwidth parts in the supplementary uplink with a single supplementary uplink bandwidth part being active at a given time. The UE shall not transmit PUSCH or PUCCH outside an active bandwidth part. For an active cell, the UE shall not transmit SRS configured by SRS-Resource outside an active bandwidth part.
Unless otherwise noted, the description in this specification applies to each of the bandwidth parts. When there is no risk of confusion, the index \(\mu\) may be dropped from \(N_{\text{BWP},i}^{\text{start},\mu}\), \(N_{\text{BWP},i}^{\text{size},\mu}\), \(N_{\text{grid},x}^{\text{start},\mu}\), and \(N_{\text{grid},x}^{\text{size},\mu}\).
4.4.6 Common MBS frequency resource #
A common MBS frequency resource is a contiguous set of common resource blocks. The starting position \(N_{\text{MBS},i}^{\text{start,}\mu}\) of the common MBS frequency resource \(i\) is defined relative to point A and the size of the common MBS frequency resource is given by \(N_{\text{MBS},i}^{\text{size,}\mu}\). Resource blocks in a common MBS frequency resource are numbered in the same way as resource blocks in clause 4.4.4.4 with \(N_{\text{BWP},i}^{\text{start,μ}}\) and \(N_{\text{BWP},i}^{\text{size,μ}}\) replaced by \(N_{\text{MBS},i}^{\text{start,}\mu}\) and \(N_{\text{MBS},i}^{\text{size,}\mu}\), respectively.
A UE is not expected to receive PDSCH or PDCCH associated with MBS transmissions scheduled with G-RNTI, G-CS-RNTI, MCCH-RNTI, or Multicast-MCCH-RNTI outside the common MBS frequency resource.
4.5 Carrier aggregation #
Transmissions in multiple="multiple" cells can be aggregated. Unless otherwise noted, the description in this specification applies to each of the serving cells.
For carrier aggregation of cells with unaligned frame boundaries, the slot offset \(N_{\text{slot, offset}}^{\text{CA}}\) between a PCell/PScell and an SCell is determined by higher-layer parameter ca-SlotOffset for the SCell. The quantity \(\mu_{\text{offset}}\) is defined as the maximum of the lowest subcarrier spacing configuration among the subcarrier spacings given by the higher-layer parameters scs-SpecificCarrierList configured for PCell/PSCell and the SCell, respectively. The slot offset \(N_{\text{slot, offset}}^{\text{CA}}\) fulfills
- when the lowest subcarrier spacing configuration among the subcarrier spacings configured for the cell is \(\mu = 2\) for both cells or \(\mu = 3\) for both cells, the start of slot 0 for the cell whose point A has a lower frequency coincides with the start of slot \({qN}_{\text{slot, offset}}^{\text{CA}}\text{mod}N_{\text{slot}}^{\text{frame},\mathbf{\mu}_{\text{offset}}}\) for the other cell where \(q = - 1\) if point A of the PCell/PSCell has a frequency lower than the frequency of point A for the SCell, otherwise \(q = 1\);
- otherwise, the start of slot 0 for the cell with the lower subcarrier spacing of the lowest subcarrier spacing given by the higher-layer parameters scs-SpecificCarrierList configured for the two cells, or the Pcell/PSCell if both cells have the same lowest subcarrier spacing given by the higher-layer parameters scs-SpecificCarrierList configured for the two cells, coincides with the start of slot \({qN}_{\text{slot, offset}}^{\text{CA}}\text{mod}N_{\text{slot}}^{\text{frame},\mathbf{\mu}_{\text{offset}}}\) for the other cell where \(q = - 1\) if the lowest subcarreier spacing configuration given by scs-SpecificCarrierList of the PCell/PSCell is smaller than or equal to the lowest subcarrier spacing given by scs-SpecificCarrierList for the SCell, otherwise \(q = 1\).

\(\[ \begin{aligned} c(n)&=(x_1(n+N_c)+x_2(n+N_c))\bmod 2\\ x_1(n+31)&=(x_1(n+3)+x_1(n))\bmod 2\\ x_2(n+31)&=(x_2(n+3)+x_2(n+2)+x_2(n+1)+x_2(n))\bmod 2 \end{aligned} \]\)
where \(N_{\text{C}} = 1600\) and the first m-sequence \(x_{1}(n)\) shall be initialized with\(x_{1}(0)=1,\; x_{1}(n)=0,\; n=1,2,\ldots,30\). The initialization of the second m-sequence, \(x_{2}(n)\), is denoted by \(c_{\text{init}} = \sum_{i=0}^{30} x_2(i)\cdot 2^i\) with the value depending on the application of the sequence.
5.2.2 Low-PAPR sequence generation type 1 #
The low-PAPR sequence \(r_{u,v}^{(\alpha,\delta)}(n)\) is defined by a cyclic shift \(\alpha\) of a base sequence \(\bar{r}_{u,v}(n)\) according to
\(r_{u,v}^{(a,\delta)}(n)=e^{j a n}\,\bar{r}_{u,v}(n),\quad 0\le n<M_{ZC}\)
where \(M_{\text{ZC}} = {{mN_{\text{sc}}^{\text{RB}}}/2^{\delta}}\) is the length of the sequence. Multiple sequences are defined from a single base sequence through different values of \(\alpha\) and \(\delta\).
Base sequences \(\bar{r}_{u,v}(n)\) are divided into groups, where \(u \in \{0,1,\ldots,29\}\) is the group number and \(\nu\) is the base sequence number within the group, such that each group contains one base sequence (\(v = 0\)) of each length \(M_{\text{ZC}} = {{mN_{\text{sc}}^{\text{RB}}}/2^{\delta}}\), \(\frac{1}{2} \le \frac{m}{2^{\delta}} \le 5\) and two base sequences (\(v = 0,1\)) of each length \(M_{\text{ZC}} = {{mN_{\text{sc}}^{\text{RB}}}/2^{\delta}}\), \(6 \le \frac{m}{2^8}\). The definition of the base sequence \(\bar{r}_{u,v}(0),\ldots,\bar{r}_{u,v}(M_{ZC}-1)\) depends on the sequence length \(M_{zC}\).

5.2.3 Low-PAPR sequence generation type 2 #
The low-PAPR sequence \(r_{u,v}^{(\alpha,\delta)}(n)\) is defined by a base sequence \({\bar{r}}_{u,v}(n)\) according to
where \(M = {{mN_{\text{sc}}^{\text{RB}}}/2^{\delta}}\) is the length of the sequence.
Base sequences \({\bar{r}}_{u,v}(n)\) are divided into groups, where \(u \in \left\{ {0,1,\ldots,29} \right\}\) is the group number and \(v\) is the base sequence number within the group, such that each group contains one base sequence (\(v = 0\)) of length \(M = {{mN_{\text{sc}}^{\text{RB}}}/2^{\delta}}\), \(1/{2 \leq {m/2^{\delta}}}\). The sequence \({\bar{r}}_{u,v}(0),\ldots,{\bar{r}}_{u,v}\left( {M - 1} \right)\) is defined by
where the definition of \({\overset{\sim}{r}}_{u,v}(i)\) depends on the sequence length.
5.2.3.1 Sequences of length 30 or larger #
For \(M \geq 30\), the sequence \({\overset{\sim}{r}}_{u,v}(i)\) is obtained as the complex-valued modulations symbols resulting from π/2-BPSK modulation as defined in clause 5.1.1 applied to the binary sequence \(c(i)\) given by clause 5.2.1, initialized with \(c_{\text{init}}\).
5.2.3.2 Sequences of length less than 30 #
For \(M = 6\), the sequence \({\overset{\sim}{r}}_{u,v}(i)\) is given by
where the value of \(\varphi(i)\) is given by Table 5.2.3.2-1.
For \(M \in \left\{ {12,18,24} \right\}\), the sequence \({\overset{\sim}{r}}_{u,v}(i)\) is obtained as the complex-valued modulations symbols resulting from π/2-BPSK modulation as defined in clause 5.1.1 applied to the binary sequence \(b(i)\) given by Tables 5.2.3.2-2 to 5.2.3.2-4.

For contention-based random access, or in absence of higher-layer configuration of \(C_{2}\) and \(C_{3}\), the value of \(C_{i}\)shall be set to the largest integer fulfilling \(T_{\text{ext}}^{'} < T_{symb,(l - 1)\text{mod7∙}2^{\mu}}^{\mu}\) for each of the values of \(i \in \left\{ 2,3 \right\}\). Text is applied to the first UL transmission scheduled by the scheduling DCI.

5.3.2 OFDM baseband signal generation for PRACH #
The time-continuous signal \(s_{l}^{(p,\mu)}(t)\) on antenna port \(p\) for PRACH is defined by
where \(t_{\text{start}}^{\mathrm{RA}} \le t < t_{\text{start}}^{\mathrm{RA}} + \left(N_u + N_{\mathrm{CP},l}^{\mathrm{RA}}\right) T_c\) and
- \(\bar{k}\) is given by clause 6.3.3;
- \(\Delta f\) is the subcarrier spacing of the initial uplink bandwidth part during initial access. If the PRACH transmission is for a candidate cell \(\Delta f\) is provided by ltm-PRACH-SubcarrierSpacing in EarlyUL-SyncConfig. Otherwise, \(\Delta f\) is the subcarrier spacing of the active uplink bandwidth part;
- \(\mu_{0}\) is the largest \(\mu\) value among the subcarrier spacing configurations by the higher-layer parameter scs-SpecificCarrierList;
- \(N_{BWP,i}^{\text{start}}\) is the lowest numbered resource block of the initial uplink bandwidth part and is derived by the higher-layer parameter initialUplinkBWP or initialUplinkBWP-RedCap during initial access and from the higher-layer parameters bwp-GenericParameters in EarlyUL-SyncConfig if the PRACH transmission is for a candidate cell. Otherwise, \(N_{BWP,i}^{\text{start}}\) is the lowest numbered resource block of the active uplink bandwidth part and is derived by the higher-layer parameter BWP-Uplink;
- \(n_{\text{RA}}^{\text{start}}\) is the frequency offset of the lowest PRACH transmission occasion in frequency domain and is given by the higher-layer parameter msgA-RO-FrequencyStart if configured and a type-2 random-access procedure is initiated as described in clause 8.1 of [5, TS 38.213], otherwise by msg1-FrequencyStart as described in clause 8.1 of [5 TS 38.213]:
- if the higher-layer parameter sbfd-RACHSingleConfig is configured, the quantity \(n_{\text{RA}}^{\text{start}}\) is defined relative the lowest-numbered physical resource block from the physical resource blocks that are both in the active uplink bandwidth part and in the uplink sub-band;
- otherwise, the quantity \(n_{\text{RA}}^{\text{start}}\) is defined relative to physical resource block 0 of the active uplink bandwidth part.
- \(n_{\mathrm{RA}}\) is the PRACH transmission occasion index in frequency domain for a given PRACH transmission occasion in one time instance as given by clause 6.3.3.2;
- \(N^{RA}_{RB}\) is the number of resource blocks occupied and is given by the parameter allocation expressed in number of RBs for PUSCH in Table 6.3.3.2-1.
- \(N_{\text{RB,UL},n}^{\text{start},\mu}\) is the start CRB index of uplink RB set \(n\) corresponding to the quantity \({RB}_{n,\text{UL}}^{start,\mu}\). The UE assumes that the RB set is defined as when the UE is not provided IntraCellGuardBandsPerSCS for an UL carrier as described in Clause 7 of [6, TS 38.214]
- \(n_{0}\) is the index of the RB set which contains the lowest PRACH transmission occasion in frequency domain indicated by \(n_{\text{RA}}^{\text{start}}\). The UE may assume that \(n_{\text{RA}}^{\text{start}}\) is configured such that each PRACH transmission occasion is fully contained within an RB set.
- \(L_{RA}\) and \(N_{u}\) are given by clause 6.3.3

where
and
- \(\Delta f_{\text{R}\text{IM}} = 15 \cdot 2^{\mu}\text{kHz}\) where \(\mu \in \left\{ 0,1 \right\}\) is the subcarrier spacing configuration for the RIM-RS;

\(\mathrm{Re}\left\{ s_{l}^{(p,\mu)}(t)\cdot e^{j 2\pi f_{0}\left(t - t_{start,l}^{\mu} - N_{CP}^{\mu} T_{c}\right)} \right\}\)
NOTE: For the uplink, the signal \(s_{l}^{(p,\mu)}(t)\) and the baseband signals part thereof should be filtered per UE implementation, as required, to meet the minimum requirements as specified in [14, 38.101-1], [15, 38.101-2], and [16, 38.101-5] for the respective frequency range.
6 Uplink #
6 .1 Overview #
6 .1.1 Overview of physical channels #
An uplink physical channel corresponds to a set of resource elements carrying information originating from higher layers. The following uplink physical channels are defined:
- Physical Uplink Shared Channel, PUSCH
- Physical Uplink Control Channel, PUCCH
- Physical Random Access Channel, PRACH
6 .1.2 Overview of physical signals #
An uplink physical signal is used by the physical layer but does not carry information originating from higher layers. The following uplink physical signals are defined:
- Demodulation reference signals, DM-RS
- Phase-tracking reference signals, PT-RS
- Sounding reference signal, SRS
6 .2 Physical resources #
The frame structure and physical resources the UE shall use when transmitting in the uplink transmissions are defined in Clause 4.
The following antenna ports are defined for the uplink:
- Antenna ports starting with 0 for demodulation reference signals for PUSCH
- Antenna ports starting with 1000 for SRS, PUSCH
- Antenna ports starting with 2000 for PUCCH
- Antenna port 4000 for PRACH
If PUSCH repetition Type B as described in clause 6.1 of [6, TS38.214] is applied to a physical channel, the UE transmission shall be such that the channel over which a symbol on the antenna port used for uplink transmission is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed if the two symbols correspond to the same actual repetition of a PUSCH transmission with repetition Type B.
If intra-slot frequency hopping is not enabled for a physical channel and PUSCH repetition Type B is not applied to the physical channel, the UE transmission shall be such that the channel over which a symbol on the antenna port used for uplink transmission is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed if the two symbols correspond to the same slot.
If intra-slot frequency hopping is enabled for a physical channel, the UE transmission shall be such that the channel over which a symbol on the antenna port used for uplink transmission is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed only if the two symbols correspond to the same frequency hop, regardless of whether the frequency hop distance is zero or not.
If DM-RS bundling is applied to PUSCH and/or PUCCH repetitions and/or transport-block processing over multiple="multiple" slots as described in clause 6.1.7 of [6, 38.214], the UE transmission shall be such that the channel over which a symbol on the antenna port used for uplink transmission is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed if the two symbols are transmitted within the same actual time-domain window.
If inter-slot OCC is applied to PUSCH as described in clause XXX of [6, 38.214], the UE transmission shall be such that the channel over which a symbol on the antenna port used for uplink transmission is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed if the two symbols are transmitted on slots within the same orthogonal cover code.
6.2.1 Muting resource #
A muting resource corresponds to a set of resource elements, defined by OFDM symbols in the time domain and a comb-2 in the frequency domain. The position in the slot of the up to two OFDM symbols, and the comb offset relative to the lowest indexed resource element of the PUSCH allocation, are given by the higher-layer parameters symbolPos and combOffset, respectively, in the PUSCH-MutingResources information element.
The UE is not expected to be configured with a muting resource within which resource elements overlap in time and frequency with a resource element used for PUSCH PT-RS when transform precoding is not enabled.
The UE shall ignore any resource elements of a muting resource that overlaps in time with an OFDM symbol used for any of
- PUSCH DM-RS
- PT-RS when transform precoding is enabled
6 .3 Physical channels #
6 .3.1 Physical uplink shared channel #
6 .3.1.1 Scrambling #
Up to two codewords \(q \in \left\{ 0,1 \right\}\) can be transmitted. In case of single-codeword transmission, \(q = 0\).
For each codeword, the block of bits \(b^{(q)}(0),\ldots,b^{(q)}\left( {M_{\text{bit}}^{(q)} - 1} \right)\), where \(M_{\text{bit}}^{(q)}\) is the number of bits in codeword \(q\) transmitted on the physical channel, shall be scrambled prior to modulation, resulting in a block of scrambled bits \({\overset{\sim}{b}}^{(q)}(0),\ldots,{\overset{\sim}{b}}^{(q)}\left( {M_{\text{bit}}^{(q)} - 1} \right)\) according to the following pseudo code
Set i = 0
while \(i < M_{\text{bit}}^{(q)}\)
if \(b^{(q)}(i) = x\) // UCI placeholder bits
\({\overset{\sim}{b}}^{(q)}(i)\) =1
else
if \(b^{(q)}(i) = y\) // UCI placeholder bits
\({\overset{\sim}{b}}^{(q)}(i)\) = \({\overset{\sim}{b}}^{(q)}\left( {i - 1} \right)\)
else
\({\overset{\sim}{b}}^{(q)}(i)\) = (\(b^{(q)}(i)\) +\(\left. c^{(q)}(i) \right)mod2\)
end if
end if
i = i + 1
end while
where x and y are tags defined in [4, TS 38.212] and where the scrambling sequence \(c^{(q)}(i)\) is given by clause 5.2.1. The scrambling sequence generator shall be initialized with

- \(n_{\text{ID}} \in \left\{ {0,1,\ldots,1023} \right\}\) equals the higher-layer parameter dataScramblingIdentityPUSCH if configured and the RNTI equals the C-RNTI, MCS-C-RNTI, SP-CSI-RNTI or CS-RNTI, and the transmission is not scheduled using DCI format 0_0 in a common search space;
- \(n_{\text{ID}} \in \left\{ {0,1,\ldots,1023} \right\}\) equals the higher-layer parameter msgA-DataScramblingIndex if configured and the PUSCH transmission is triggered by a Type-2 random access procedure as described in clause 8.1A of [5, TS 38.213];
- \(n_{\text{ID}} = N_{\text{ID}}^{\text{cell}}\) otherwise
- \(n_{\text{RAPID}}\) is the index of the random-access preamble transmitted for msgA as described in clause 5.1.3A of [11, TS 38.321]
and where \(n_{\mathrm{RNTI}}\) equals the RA-RNTI for msgA and otherwise corresponds to the RNTI associated with the PUSCH transmission as described in clause 6.1 of [6, TS 38.214] and clause 8.3 of [5, TS 38.213].
6 .3.1.2 Modulation #
For each codeword \(q\), the block of scrambled bits \({\overset{\sim}{b}}^{(q)}(0),\ldots,{\overset{\sim}{b}}^{(q)}\left( {M_{\text{bit}}^{(q)} - 1} \right)\) shall be modulated as described in clause 5.1 using one of the modulation schemes in Table 6.3.1.2-1, resulting in a block of complex-valued modulation symbols \({\overset{\sim}{d}}^{(q)}(0),\ldots,{\overset{\sim}{d}}^{(q)}\left( M_{\text{symb}}^{(q)} - 1 \right)\).
Table 6.3.1.2-1: Supported modulation schemes.
Transform precoding disabled | Transform precoding enabled | ||
Modulation scheme | Modulation order \(Q_m\) | Modulation scheme | Modulation order \(Q_m\) |
|
| π/2-BPSK | 1 |
QPSK | 2 | QPSK | 2 |
16QAM | 4 | 16QAM | 4 |
64QAM | 6 | 64QAM | 6 |
256QAM | 8 | 256QAM | 8 |

The block of complex-valued modulation symbols \({\overset{\sim}{d}}^{(q)}(0),\ldots,{\overset{\sim}{d}}^{(q)}\left( M_{\text{symb}}^{(q)} - 1 \right)\) shall be multiplied with the quantity \(w_{i}\) to form the block of complex-valued modulation symbols \(d^{(q)}(0),\ldots,d^{(q)}\left( M_{\text{symb}}^{(q)} - 1 \right)\).
If the UE transmits PUSCH using repetition type A with OCC
- the quantity \(w_{i}\) is obtained according to clause 6.1.2.1 of [6, 38.214];
otherwise,
- \(w_{i} = 1\).
6 .3.1.3 Layer mapping #
The complex-valued modulation symbols for each of the codewords to be transmitted shall be mapped onto up to four layers according to Table 7.3.1.3-1. Complex-valued modulation symbols \(d^{(q)}(0),\ldots,d^{(q)}\left( {M_{\text{symb}}^{(q)} - 1} \right)\) for codeword \(q\) shall be mapped onto the layers \(x(i) = \begin{bmatrix} {x^{(0)}(i)} & \ldots & {x^{({\upsilon - 1})}(i)} \end{bmatrix}^{\text{T}}\), \(i = 0,1,\ldots,M_{\text{symb}}^{\text{layer}} - 1\) where \(\upsilon\) is the number of layers and \(M_{\text{symb}}^{\text{layer}}\) is the number of modulation symbols per layer.
6 .3.1.4 Transform precoding #
If transform precoding is not enabled according to 6.1.3 of [6, TS38.214], \(y^{(\lambda)}(i) = x^{(\lambda)}(i)\) for each layer \(\lambda = 0,1,\ldots,\nu - 1\).
If transform precoding is enabled according to 6.1.3 of [6, TS38.214], \(\upsilon = 1\) and \(\tilde{x}^{(0)}(i)\) depends on the configuration of phase-tracking reference signals.
If the procedure in [6, TS 38.214] indicates that phase-tracking reference signals are not being used, the block of complex-valued symbols \(x^{(0)}(0),\ldots,x^{(0)}\left( {M_{\text{symb}}^{\text{layer}} - 1} \right)\) for the single layer \(\lambda = 0\) shall be divided into sets, each corresponding to one OFDM symbol and where set \(l\) contains \(M_{\text{sc},l}^{\text{PUSCH}}\) symbols and is mapped to the complex-valued symbols \({\overset{\sim}{x}}_{l}^{(0)}\left( i^{'} \right)\), corresponding to OFDM symbol \(l\) prior to transform precoding, with \(i' \in \left\{ {0,1,\ldots,M_{\text{sc},l}^{\text{PUSCH}} - 1} \right\}\).
If the procedure in [6, TS 38.214] indicates that phase-tracking reference signals are being used, the block of complex-valued symbols \(x^{(0)}(0),\ldots,x^{(0)}\left( {M_{\text{symb}}^{\text{layer}} - 1} \right)\) shall be divided into sets, each set corresponding to one OFDM symbol, and where set \(l\) contains \(M_{\text{sc}\text{,}l}^{\text{PUSCH}} - \varepsilon_{l}N_{\text{samp}}^{\text{group}}N_{\text{group}}^{\text{PTRS}}\) symbols and is mapped to the complex-valued symbols \({\overset{\sim}{x}}_{l}^{(0)}\left( i^{'} \right)\) corresponding to OFDM symbol \(l\) prior to transform precoding, with \(i' \in \left\{ {0,1,\ldots,M_{\text{sc},l}^{\text{PUSCH}} - 1} \right\}\) and \(i' \neq m\). The index \(m\) of PT-RS samples in set \(l\), the number of samples per PT-RS group \(N_{\text{samp}}^{\text{group}}\), and the number of PT-RS groups \(N_{\text{group}}^{\text{PT-RS}}\) are defined in clause 6.4.1.2.2.2. The quantity \(\varepsilon_l = 1\) when OFDM symbol \(l\) contains one or more PT-RS samples, otherwise \(\varepsilon_l = 0\).
Transform precoding shall be applied according to
\({\overset{\sim}{y}}_{l}^{(0)}(k){} = \frac{1}{\sqrt[{}]{M_{\text{sc,}\text{l}}^{\text{PUSCH}}}}\sum\limits_{i = 0}^{M_{\text{sc,}\text{l}}^{\text{PUSCH}} - 1}{{\overset{\sim}{x}}_{l}^{(0)}(i)e^{- j\frac{2\pi ik}{M_{\text{sc,}\text{l}}^{\text{PUSCH}}}}}\)
\(k{} = 0,\ldots,M_{\text{sc,}\text{l}}^{\text{PUSCH}} - 1\)
resulting in a set of blocks of complex-valued symbols \({\overset{\sim}{y}}_{l}^{(0)}(0),\ldots,{\overset{\sim}{y}}_{l}^{(0)}\left( M_{\text{sc,}\text{l}}^{\text{PUSCH}} - 1 \right)\) that shall be concatenated in order of increasing \(l\) to form \(y^{(0)}(0),\ldots,y^{(0)}\left( {\overset{\sim}{M}}_{\text{symb}}^{\text{layer}} - 1 \right)\). The total number of modulations symbols \({\overset{\sim}{M}}_{\text{symb}}^{\text{layer}}\) equals \(M_{\text{symb}}^{\text{layer}}\) with any PT-RS samples added.
The variable\(M_{sc}^{\mathrm{PUSCH}} = M_{RB}^{\mathrm{PUSCH}} \cdot N_{sc}^{\mathrm{RB}}\), where \(M_{RB}^{\text{PUSCH}}\) represents the bandwidth of the PUSCH in terms of resource blocks, and shall fulfil
\(M_{\mathrm{RB}}^{\mathrm{PUSCH}} = 2^{a_2}\cdot 3^{a_3}\cdot 5^{a_5}\)
where \(a_2, a_3, a_5\) is a set of non-negative integers.
The variable \(M_{\text{sc,}\text{l}}^{\text{PUSCH}}\) equals \(M_{\text{sc}}^{\text{PUSCH}}/2\) when OFDM symbol \(l\) is occupied by a muting resource, otherwise \(M_{\text{sc,}\text{l}}^{\text{PUSCH}} = M_{\text{sc}}^{\text{PUSCH}}\).
6 .3.1.5 Precoding #
The block of vectors \(\begin{bmatrix} {y^{(0)}(i)} & \ldots & {y^{({\upsilon - 1})}(i)} \end{bmatrix}^{\text{T}}\) shall be precoded according to
where \(i = 0,1,\ldots,M_{\text{symb}}^{\text{ap}} - 1\), \(M_{\text{symb}}^{\text{ap}} = {\overset{\sim}{M}}_{\text{symb}}^{\text{layer}}\). The set of antenna ports \(\left\{ {p_{0},\ldots,p_{\rho - 1}} \right\}\) shall be determined according to the procedure in [6, TS 38.214].
For non-codebook-based transmission, the precoding matrix \(W\) equals the identity matrix.
For codebook-based transmission, the precoding matrix \(W\) depends on the number of antenna ports used for the transmission:
- for single-layer transmission on a single antenna port, \(W = 1\);
- for transmissions using 2, or 4 antenna ports, \(W\) is given by Tables 6.3.1.5-1 to 6.3.1.5-7;
- for transmissions using 3 antenna ports when 4portSRS_3TX is configured, \(W\) is given by Tables 6.3.1.5-48 to 6.3.1.5-50;
- for transmissions using 8 antenna ports, \(W\) is given by
where
- the subscripts \(i\) and \(f(i)\) denote the row of the respective matrix;
- \(f(i)\) is given by Table 6.3.1.5-8;
- the intermediate precoding matrix \(W'\) is given by Tables 6.3.1.5-9 to 6.3.1.5-24, 6.3.1.5-29 to 6.3.1.5-36, and 6.3.1.5-39 to 6.3.1.5-47 with \(0_{m \times n}\) representing the all-zero matrix with \(m\) rows and \(n\) columns;
- the submatrices \({\bar{W}}_{m,n}\) are given by Tables 6.3.1.5-25 to 6.3.1.5-28 and 6.3.1.5-37 to 6.3.1.5-38.
The TPMI index used in the tables above is obtained from the DCI scheduling the uplink transmission or the higher layer parameters according to the procedure in [6, TS 38.214].
When the higher-layer parameter txConfig is not configured, the precoding matrix \(W = 1\).

6 .3.1.6 Mapping to virtual resource blocks #
For each of the antenna ports used for transmission of the PUSCH, each symbol in the block of complex-valued symbols \(z^{(p)}(0),\ldots,z^{(p)}\bigl(M_{\mathrm{symb}}^{\mathrm{ap}}-1\bigr)\) shall be multiplied with \(\sqrt[{}]{2}\) if the symbol corresponds to an OFDM symbol occupied by a muting resource, and by 1 otherwise, and further be multiplied with the amplitude scaling factor \(\beta_{\mathrm{PUSCH}}\) in order to conform to the transmit power specified in [5, TS 38.213] and mapped in sequence starting with \(z^{(p)}(0)\) to resource elements \((k',l)_{p,\mu}\) in the virtual resource blocks assigned for transmission which meet all of the following criteria:
- they are in the virtual resource blocks assigned for transmission, and
- the corresponding resource elements in the corresponding physical resource blocks are not used for transmission of the associated DM-RS, PT-RS, or DM-RS intended for other co-scheduled UEs as described in clause 6.4.1.1.3, and
- the corresponding resource elements in the corresponding physical resource blocks do not correspond to a muting resource.
The mapping to resource elements \((k',l)_{p,\mu}\) allocated for PUSCH according to [6, TS 38.214] shall be in increasing order of first the index \(k'\) over the assigned virtual resource blocks, where \(k^{'} = 0\) is the first subcarrier in the lowest-numbered virtual resource block assigned for transmission, and then the index \(l\), with the starting position given by [6, TS 38.214].
6.3.1. 7 Mapping from virtual to physical resource blocks #
Virtual resource blocks shall be mapped to physical resource blocks according to non-interleaved mapping.
For non-interleaved VRB-to-PRB mapping for uplink resource allocation types 0 and 1 [6, TS 38.214], virtual resource block \(n\) is mapped to physical resource block \(n\) except for PUSCH scheduled by RAR UL grant or PUSCH scheduled by DCI format 0_0 with CRC scrambled by TC-RNTI in active uplink bandwidth part \(i\) starting at \(N_{\text{BWP},i}^{\text{start}}\), including all resource blocks of the initial uplink bandwidth part starting at \(N_{\text{BWP},0}^{\text{start}}\), and having the same subcarrier spacing and cyclic prefix as the initial uplink bandwidth part, in which case virtual resource block \(n\) is mapped to physical resource block \(n + N_{\text{BWP},0}^{\text{start}} - N_{\text{BWP},i}^{\text{start}}\).
For non-interleaved VRB-to-PRB mapping for uplink resource allocation type 2 [6, TS 38.214], virtual resource block \(n\) is mapped to physical resource block \(n\).
6 .3.2 Physical uplink control channel #
6.3.2.1 General #
The physical uplink control channel supports multiple="multiple" formats as shown in Table 6.3.2.1-1. In case intra-slot frequency hopping is configured for PUCCH formats 1, 3, or 4 according to clause 9.2.1 of [5, TS38.213], the number of symbols in the first hop is given by \(\left\lceil \frac{N^{\mathrm{PUCCH}}_{\mathrm{symb}}}{2} \right\rceil\) where \(N_{\mathrm{symb}}^{\mathrm{PUCCH}}\) is the length of the PUCCH transmission in OFDM symbols.
Table 6.3.2.1-1: PUCCH formats.
PUCCH format | Length in OFDM symbols \(N_{\mathrm{symb}}^{\mathrm{PUCCH}}\) | Number of bits |
0 | 1 – 2 | ≤2 |
1 | 4 – 14 | ≤2 |
2 | 1 – 2 | >2 |
3 | 4 – 14 | >2 |
4 | 4 – 14 | >2 |
6.3.2.2 Sequence and cyclic shift hopping #
PUCCH formats 0, 1, 3, and 4 use sequences \(r_{u,v}^{({\alpha,\delta})}(n)\) given by clause 5.2.2 with \(\delta = 0\) where the sequence group \(u\) and the sequence number \(v\) depend on the sequence hopping in clause 6.3.2.2.1 and the cyclic shift \(\alpha\) depends on the cyclic shift hopping in clause 6.3.2.2.2.
6.3.2.2.1 Group and sequence hopping #
The sequence group \(u = \left( {f_{\text{gh}} + f_{\text{ss}}} \right)\text{mod}30\) and the sequence number \(v\) within the group depends on the higher-layer parameter pucch-GroupHopping:
- if pucch-GroupHopping equals 'neither'
\(\begin{aligned} f_{gh} &= 0\\ f_{ss} &= n_{\mathrm{ID}} \bmod 30\\ v &= 0 \end{aligned}\)
where \(n_{ID}\) is given by the higher-layer parameter hoppingId if configured, otherwise \(n_{\text{ID}} = N_{\text{ID}}^{\text{cell}}\).
- if pucch-GroupHopping equals 'enable'
\(f_{gh}=\left(\sum_{m=0}^{7}2^{m}c\!\left(8\bigl(2n_{s,f}^{\mu}+n_{hop}\bigr)+m\right)\right)\bmod 30 f_{ss}=n_{ID}\bmod 30 v=0\)
where the pseudo-random sequence \(c(i)\) is defined by clause 5.2.1 and shall be initialized at the beginning of each radio frame with \(c_{\text{init}}=\left[\frac{n_{\text{ID}}}{30}\right]\) where \(n_{ID}\) is given by the higher-layer parameter hoppingId if configured, otherwise \(n_{\text{ID}} = N_{\text{ID}}^{\text{cell}}\).
- if pucch-GroupHopping equals 'disable'
\(\[ \begin{aligned} f_{gh} &= 0 \\ f_{ss} &= n_{\mathrm{ID}} \bmod 30 \\ \nu &= c\left(2n_{s,f}^{\mu} + n_{hop}\right) \end{aligned} \]\)
where the pseudo-random sequence \(c(i)\) is defined by clause 5.2.1 and shall be initialized at the beginning of each radio frame with \(c_{\text{init}} = 2^{5}\left\lfloor {n_{\text{ID}}/30} \right\rfloor + \left( {n_{\text{ID}}\text{mod}30} \right)\) where \(n_{ID}\) is given by the higher-layer parameter hoppingId if configured, otherwise \(n_{\text{ID}} = N_{\text{ID}}^{\text{cell}}\).
The frequency hopping index \(n_{\text{hop}} = 0\) if intra-slot frequency hopping is disabled="disabled" by the higher-layer parameter intraSlotFrequencyHopping. If frequency hopping is enabled by the higher-layer parameter intraSlotFrequencyHopping, \(n_{\mathrm{hop}}=0\) for the first hop and \(n_{\mathrm{hop}} = 1\) for the second hop.
6.3.2.2.2 Cyclic shift hopping #
The cyclic shift \(\alpha\) varies as a function of the symbol and slot number according to
where
- \(n_{\text{s,f}}^{\mu}\) is the slot number in the radio frame
- \(l\) is the OFDM symbol number in the PUCCH transmission where \(l = 0\) corresponds to the first OFDM symbol of the PUCCH transmission,
- \(l'\) is the index of the OFDM symbol in the slot that corresponds to the first OFDM symbol of the PUCCH transmission in the slot given by [5, TS 38.213]
- \(m_{0}\) is given by [5, TS 38.213] for PUCCH format 0 and 1 while for PUCCH format 3 and 4 is defined in clause 6.4.1.3.3.1
- \(m_{cs}=0\) except for PUCCH format 0 when it depends on the information to be transmitted according to clause 9.2 of [5, TS 38.213].
- \(m_{\text{int}}\) is given by
- \(m_{\text{int}} = {5n}_{\text{IRB}}^{\mu}\) for PUCCH formats 0 and 1 if PUCCH shall use interlaced mapping according to any of the higher-layer parameters useInterlacePUCCH-PUSCH in BWP-UplinkCommon or useInterlacePUCCH-PUSCH in BWP-UplinkDedicated, where \(n_{\text{IRB}}^{\mu}\) is the resource block number within the interlace;
- \(m_{\text{int}} = 0\) otherwise
The function \(n_{cs}(n_c,l)\) is given by
\(n_{\text{cs}}\left( {n_{\text{s,f}}^{\mu},l} \right) = \sum\limits_{m = 0}^{7}2^{m}c\left( {8N_{\text{symb}}^{\text{slot}}n_{\text{s,f}}^{\mu} + 8l + m} \right)\)
where the pseudo-random sequence \(c(i)\) is defined by clause 5.2.1. The pseudo-random sequence generator shall be initialized with \(c_{\text{init}} = n_{\text{ID}}\), where \(n_{ID}\) is given by the higher-layer parameter hoppingId if configured, otherwise \(n_{\text{ID}} = N_{\text{ID}}^{\text{cell}}\).
6.3.2. 3 PUCCH format 0 #
6.3.2. 3.1 Sequence generation #
The sequence \(x(n)\) shall be generated according to
where \(r_{u,v}^{({\alpha,\delta})}(n)\) is given by clause 6.3.2.2 with \(m_{cs}\) depending on the information to be transmitted according to clause 9.2 of [5, TS 38.213]. The quantity \(M_{\text{RB}}^{\text{PUCCH,}0}\) is given by clause 9.2.1 of [5, TS 38.213].
6.3.2. 3.2 Mapping to physical resources #
The sequence \(x(n)\) shall be multiplied with the amplitude scaling factor \(\beta_{\mathrm{PUCCH},0}\) in order to conform to the transmit power specified in [5, TS 38.213] and mapped in sequence starting with \(x(0)\) to resource elements \(\left( {k,l} \right)_{p,\mu}\) assigned for transmission according to clause 9.2.1 of [5, TS 38.213] in increasing order of first the index \(k\) over the assigned physical resources spanning \(M_{\text{RB}}^{\text{PUCCH,}0}\) resource blocks, and then the index \(l\) on antenna port \(p = 2000\).
For interlaced transmission, the mapping operation shall be repeated for each resource block in the interlace and in the active bandwidth part over the assigned physical resource blocks according to clause 9.2.1 of [5, TS 38.213], with the resource-block dependent sequence generated according to clause 6.3.2.2.
6.3.2. 4 PUCCH format 1 #
6.3.2. 4.1 Sequence modulation #
The block of bits \(b(0),\ldots,b(M_{bit}-1)\) shall be modulated as described in clause 5.1 using BPSK if \(M_{bit}=1\) and QPSK if \(M_{bit}=2\), resulting in a complex-valued symbol \(d(0)\). The complex-valued symbol <br>\(d(0)\) shall be multiplied with a sequence \(r_{u,v}^{({\alpha,\delta})}(n)\) according to
where \(r_{u,v}^{({\alpha,\delta})}(n)\) is given by clause 6.3.2.2. The quantity \(M_{\text{RB}}^{\text{PUCCH,}1}\) is given by clause 9.2.1 of [5, TS 38.213].
The block of complex-valued symbols \(y(0),\ldots,y\left( {M_{\text{RB}}^{\text{PUCCH},1}N_{\text{sc}}^{\text{RB}} - 1} \right)\) shall be block-wise spread with the orthogonal sequence \(w_i(m)\) according to
where \(N_{\text{SF},m'}^{\text{PUCCH},1}\) is given by Table 6.3.2.4.1-1. Intra-slot frequency hopping shall be assumed when the higher-layer parameter intraSlotFrequencyHopping is provided, regardless of whether the frequency-hop distance is zero or not, and interlaced mapping is not enabled, otherwise no intra-slot frequency hopping shall be assumed.
The orthogonal sequence \(w_i(m)\) is given by Table 6.3.2.4.1-2 where \(i\) is the index of the orthogonal sequence to use according to clause 9.2.1 of [5, TS 38.213]. In case of a PUCCH transmission spanning multiple="multiple" slots according to clause 9.2.6 of [5, TS38.213], the complex-valued symbol \(d(0)\) is repeated for the subsequent slots.

The set of random-access preambles \(x_{u,v}(n)\) shall be generated according to
\(\[ x_{u,v}(n)=x_u\big((n+C_v)\bmod L_{RA}\big) \] \[ x_u(i)=e^{-j\frac{\pi u\, i(i+1)}{L_{RA}}},\quad i=0,1,\ldots,L_{RA}-1 \]\)
from which the frequency-domain representation shall be generated according to
\(y_{u,v}(n)=\sum_{m=0}^{L_{RA}-1} x_{u,v}(m)\cdot e^{-j\frac{2\pi mn}{L_{RA}}}\)
where \(L_{RA}=839\), \(L_{RA}=139\), \(L_{\text{RA}} = 1151\), or \(L_{\text{RA}} = 571\) depending on the PRACH preamble format as given by Tables 6.3.3.1-1 and 6.3.3.1-2.
There are 64 preambles defined in each time-frequency PRACH occasion, enumerated in increasing order of first increasing cyclic shift \(C_{v}\) of a logical root sequence, and then in increasing order of the logical root sequence index, starting with the index obtained from the higher-layer parameter prach-RootSequenceIndex or rootSequenceIndex-BFR or by msgA-PRACH-RootSequenceIndex if configured and a type-2 random-access procedure is initiated as described in clause 8.1 of [5, TS 38.213] or by prach-RootSequenceIndex in EarlyUL-SyncConfig if the PRACH transmission is for a candidate cell. Additional preamble sequences, in case 64 preambles cannot be generated from a single root Zadoff-Chu sequence, are obtained from the root sequences with the consecutive logical indexes until all the 64 sequences are found. The logical root sequence order is cyclic; the logical index 0 is consecutive to \(L_{\text{RA}} - 2\). The sequence number \(\boldsymbol{u}\) is obtained from the logical root sequence index according to Tables 6.3.3.1-3 to 6.3.3.1-4B.
The cyclic shift \(C_{v}\) is given by
\(\[ C_v=\begin{cases} v N_{CS}, & v=0,1,\ldots,\left\lfloor \dfrac{L_{RA}}{N_{CS}} \right\rfloor-1,\; N_{CS}\neq 0 \ \text{for unrestricted sets},\\ 0, & N_{CS}=0 \ \text{for unrestricted sets},\\ \bar d_{\text{start}}\left\lfloor \dfrac{v}{n^{RA}_{\text{shift}}}\right\rfloor + \bigl(v \bmod n^{RA}_{\text{shift}}\bigr) N_{CS}, & v=0,1,\ldots,w-1 \ \text{for restricted sets type A and B},\\ \bar d_{\text{start}}+(v-w)N_{CS}, & v=w,\ldots,w+\bar n^{RA}_{\text{shift}}-1 \ \text{for restricted sets type B},\\ \bar d_{\text{start}}+(v-w-\bar n^{RA}_{\text{shift}})N_{CS}, & v=w+\bar n^{RA}_{\text{shift}},\ldots,w+\bar n^{RA}_{\text{shift}}+\bar n^{RA}_{\text{shift}}-1 \ \text{for restricted sets type B}. \end{cases} \] \[ w=n^{RA}_{\text{shift}}\,n^{RA}_{\text{group}}+\bar n^{RA}_{\text{shift}} \]\)
where \(N_{cs}\) is given by Tables 6.3.3.1-5 to 6.3.3.1-7. The type of restricted sets (unrestricted, restricted type A, restricted type B) is given by
- the higher-layer parameter msgA-RestrictedSetConfig, if provided;
- or the higher-layer parameter ltm-restrictedSetConfig associated with a candidate cell indicated in Cell indicator field of a PDCCH order, if provided;
- otherwise, the higher-layer parameter restrictedSetConfig.

\(\[ d_u = \begin{cases} q, & 0 \le q < \frac{L_{\mathrm{RA}}}{2} \\ L_{\mathrm{RA}} - q, & \text{otherwise} \end{cases} \]\)
where \(q\) is the smallest non-negative integer that fulfils \((qu)\bmod L_{RA} = 1\). The parameters for restricted sets of cyclic shifts depend on \(d_{u}\).
For restricted set type A, the parameters are given by:

- for \(\frac{L_{RA}+N_{CS}}{4} \le d_u < \frac{2L_{RA}}{7}\)

- for \(2L_{RA}/7 \le d_u \le (L_{RA}-N_{CS})/3\)

- for \((L_{RA}+N_{CS})/3\le d_u<2L_{RA}/5\)
\(\[ \begin{aligned} n_{\mathrm{shift}}^{\mathrm{RA}} &= \left\lfloor \frac{3 d_u - L_{\mathrm{RA}}}{N_{\mathrm{CS}}} \right\rfloor \\ d_{\mathrm{start}} &= 3 d_u - L_{\mathrm{RA}} + n_{\mathrm{shift}}^{\mathrm{RA}} N_{\mathrm{CS}} \\ \bar{d}_{\mathrm{start}} &= 0 \\ \bar{\bar{d}}_{\mathrm{start}} &= 0 \\ n_{\mathrm{group}}^{\mathrm{RA}} &= \left\lfloor \frac{d_u}{d_{\mathrm{start}}} \right\rfloor \\ \bar{n}_{\mathrm{shift}}^{\mathrm{RA}} &= \max\!\left( \left\lfloor \frac{L_{\mathrm{RA}} - 2 d_u - n_{\mathrm{group}}^{\mathrm{RA}} d_{\mathrm{start}}}{N_{\mathrm{CS}}} \right\rfloor ,\, 0 \right) \\ \bar{n}_{\mathrm{shift}}^{\mathrm{RA}} &= 0 \\ \bar{\bar{n}}_{\mathrm{shift}}^{\mathrm{RA}} &= 0 \end{aligned} \]\)

6.3.3.2 Mapping to physical resources #
The preamble sequence shall be mapped to physical resources according to
\(\begin{aligned} a_k^{(p,\mathrm{RA})} &= \beta_{\mathrm{PRACH}} y_{u,v}(k) \\ k &= 0,1,\ldots,L_{\mathrm{RA}}-1 \end{aligned}\)
where \(\beta_{\mathrm{PRACH}}\) is an amplitude scaling factor in order to conform to the transmit power specified in [5, TS38.213], and \(\[p=4000\]\) is the antenna port. Baseband signal generation shall be done according to clause 5.3 using the parameters in Table 6.3.3.1-1 or Table 6.3.3.1-2 with \(\bar{k}\) given by Table 6.3.3.2-1.
Random access preambles can only be transmitted in the time resources obtained from Tables 6.3.3.2-2 to 6.3.3.2-4 and depends on FR1, FR2, or FR2-NTN and the spectrum type as defined in [8, TS38.104] or [17, TS38.108]. The PRACH configuration index in Tables 6.3.3.2-2 to 6.3.3.2-4 is
- for Table 6.3.3.2-3 given by the higher-layer parameter prach-ConfigurationIndex, or by msgA-PRACH-ConfigurationIndex if configured; and
- for Tables 6.3.3.2-2 and 6.3.3.2-4 given by the higher-layer parameter prach-ConfigurationIndex, or by msgA-PRACH-ConfigurationIndex if configured.
For the IAB-MT part of an IAB-node, the following applies:
- if the higher-layer parameter prach-ConfigurationPeriodScaling-IAB is configured, the variable \(x\) used in \(n_{\text{f}}\text{mod}x = y\) of Tables 6.3.3.2-2 to 6.3.3.2-4 shall be replaced by \(x_{\text{IAB}}\) , where \(x_{\text{IAB}} = \delta x\) and \(\delta\) is given by the higher-layer parameter prach-ConfigurationPeriodScaling-IAB and the IAB-node does not expect \(x_{\text{IAB}}\) to be larger than 64;
- if the higher-layer parameter prach-ConfigurationFrameOffset-IAB is configured, the variable \(y\) used in \(n_{f}\text{mod}x = y\) of Tables 6.3.3.2-2 to 6.3.3.2-4 shall be replaced by \(y_{\text{IAB}} = \left( {y + \Delta y} \right)\text{mod}x\) where \(\Delta y\) is given by the higher-layer parameter prach-ConfigurationFrameOffset-IAB, and \(xisthevalueused\text{in}n_{f}\text{mod}x = y\);
- if the higher-layer parameter prach-ConfigurationSOffset-IAB is configured, the subframe number \(s_{\text{n}}\) from Tables 6.3.3.2-2 to 6.3.3.2-3 and the slot number \(s_{\text{n}}\) from Table 6.3.3.2-4 shall be replaced by \(\left( {s_{\text{n}} + \Delta s} \right)\text{mod}L\) where \(\Delta s \in \left\{ {0,1,\ldots,L - 1} \right\}\) is given by the higher-layer parameter prach-ConfigurationSOffset-IAB, and \(L\) is the number of subframes in a frame when using Tables 6.3.3.2-2 to 6.3.3.2-3 and the number of slots in a frame for 60 kHz subcarrier spacing when using in Table 6.3.3.2-4.
Random access preambles can only be transmitted in the frequency resources given by either the higher-layer parameter msg1-FrequencyStart or msgA-RO-FrequencyStart if configured as described in clause 8.1 of [5 TS 38.213]. The PRACH frequency resources \(n_{\text{RA}} \in \left\{ {0,1,\ldots,M - 1} \right\}\), where \(M\) equals the higher-layer parameter msg1-FDM or msgA-RO-FDM if configured, are numbered in increasing order within the initial uplink bandwidth part during initial access, starting from the lowest frequency. Otherwise, \(n_{\text{RA}}\) are numbered in increasing order within the active uplink bandwidth part, starting from the lowest frequency.
For operation with shared spectrum channel access, for \(L_{RA} = 139\), a UE expects to be provided with higher-layer parameter msg1-FrequencyStart or msgA-RO-FrequencyStart if configured, and higher-layer parameter msg1-FDM or msgA-RO-FDM if configured, such that a random-access preamble is confined within a single RB set. The UE assumes that the RB set is defined as when the UE is not provided intraCellGuardBandsPerSCS for an UL carrier as described in Clause 7 of [6, TS 38.214].
For operation with shared spectrum channel access, for \(L_{RA} = 571\) or \(1151\) and Type-2 random access, a UE expects to be provided with higher-layer parameter msgA-RO-FDM equals to one.
For the purpose of slot numbering in the tables, the following subcarrier spacing shall be assumed:
- 15 kHz for FR1
- 60 kHz for FR2 and FR2-NTN.
For handover purposes to a target cell in paired or unpaired spectrum where the target cell uses \(L_{\max} = 4\), the UE may assume the absolute value of the time difference between radio frame \(i\) in the current cell and radio frame \(i\) in the target cell is less than \(153600T_{\text{s}}\) if the association pattern period in clause 8.1 of [5, TS 38.213] is not equal to 10 ms.
For inter frequency handover purposes where the source cell is either in paired or unpaired spectrum and the target cell is in unpaired spectrum and uses \(L_{\max} = 8\), the UE may assume the absolute value of the time difference between radio frame \(i\) in the current cell and radio frame \(i\) in the target cell is less than \(76800T_{s}.\)

6.4.1.1.1.2 Sequence generation when transform precoding is enabled #
If transform precoding for PUSCH is enabled, the reference-signal sequence \(r(n)\) shall be generated according to
\(\begin{aligned} r(n) &= r_{u,v}^{(\alpha,\delta)}(n)\\ n &= 0,1,\ldots,\frac{M_{sc}^{\mathrm{PUSCH}}}{2^{\delta}} - 1 \end{aligned}\)
where \(r_{u,v}^{({\alpha,\delta})}(n)\) with \(\delta = 1\) depends on the configuration:
- if the higher-layer parameter dmrs-UplinkTransformPrecoding is configured, π/2-BPSK modulation is used for PUSCH, and the PUSCH transmission is not a msg3 transmission, and the transmission is not scheduled using DCI format 0_0 in a common search space, \(r_{u,v}^{({\alpha,\delta})}(n)\) is given by clause 5.2.3 with \(c_{\text{init}}\) given by
where \(n_{\text{SCID}} = 0\) unless given by the DCI according to clause 7.3.1.1.2 in [4, TS38.212] for a transmission scheduled by DCI format 0_1, or given by the DCI according to clause 7.3.1.1.3 in [4, TS38.212] for a transmission scheduled by DCI format 0_2 if the antenna ports field in the DCI format 0_2 is not 0 bit, or given by the DCI according to clause 7.3.1.1.4 in [4, TS38.212] for a transmission scheduled by DCI format 0_3, or given by the higher-layer parameter antennaPort for a PUSCH transmission scheduled by a type-1 configured grant; and

- \(N_{\text{ID}}^{0} \in \left\{ {0,1,\ldots,65535} \right\}\) is given by the higher-layer parameter pi2BPSK-ScramblingID0 in the DMRS-UplinkConfig IE if provided and the PUSCH is scheduled by DCI format 0_0 with the CRC scrambled by C-RNTI, MCS-C-RNTI, or CS-RNTI, or by DCI format 0_2 if the antenna ports field in the DCI format 0_2 is 0 bit;
- \(N_{\text{ID}}^{n_{\text{SCID}}} = N_{\text{ID}}^{\text{cell}}\) otherwise;
- otherwise, \(r_{u,v}^{({\alpha,\delta})}(n)\) is given by clause 5.2.2 with \(\alpha = 0\).
The sequence group \(u = \left( {f_{\text{gh}} + n_{\text{ID}}^{\text{RS}}} \right)\text{mod}30\), where \(n_{\text{ID}}^{\text{RS}}\) is given by
- \(n_{\text{ID}}^{\text{RS}} = n_{\text{ID}}^{\text{PUSCH}}\) if \(n_{\text{ID}}^{\text{PUSCH}}\) is configured by the higher-layer parameter nPUSCH-Identity in the DMRS-UplinkConfig IE, and
- the higher-layer parameter dmrs-UplinkTransformPrecoding is not configured or the higher-layer parameter dmrs-UplinkTransformPrecoding is configured and π/2-BPSK modulation is not used for PUSCH, and
- the PUSCH is neither scheduled by RAR UL grant nor scheduled by DCI format 0_0 with CRC scrambled by TC-RNTI according to clause 8.3 in [5, TS 38.213];
- \(n_{\text{ID}}^{\text{RS}} = N_{\text{ID}}^{n_{\text{SCID}}}\) if the higher-layer parameter dmrs-UplinkTransformPrecoding is configured, π/2-BPSK modulation is used for PUSCH, the PUSCH transmission is not a msg3 transmission, and the transmission is not scheduled using DCI format 0_0 in a common search space;
- \(n_{\text{ID}}^{\text{RS}} = N_{\text{ID}}^{\text{cell}}\) otherwise
where \(f_{gh}\) and the sequence number \(v\) are given by:
- if neither group, nor sequence hopping is enabled
\(\begin{aligned} f_{gh}=0\\ v=0 \end{aligned}\)
- if group hopping is enabled and sequence hopping is disabled="disabled"
\(f_{gh}=\left(\sum_{m=0}^{7}2^{m}c\!\left(8\left(N_{\text{symb}}^{\text{slot}}\,n_{s,f}^{\mu}+l\right)+m\right)\right)\bmod 30 v=0\)
where the pseudo-random sequence \(c(i)\) is defined by clause 5.2.1 and shall be initialized with \(c_{init} = \left\lfloor \frac{n_{ID}^{\mathrm{RS}}}{30} \right\rfloor\) at the beginning of each radio frame
- if sequence hopping is enabled and group hopping is disabled
\(f_{gh}=0 v=\begin{cases} c\left(N_{symb}^{\mathrm{slot}}\,n_{s,f}^{\mu}+l\right) & \text{if } M_{ZC}\ge 6\,N_{sc}^{\mathrm{RB}}\\ 0 & \text{otherwise} \end{cases}\)
where the pseudo-random sequence \(c(i)\) is defined by clause 5.2.1 and shall be initialized with \(c_{\mathrm{init}} = n^{\mathrm{RS}}_{\mathrm{ID}}\) at the beginning of each radio frame.
The hopping mode is controlled by higher-layer parameters:
- for PUSCH transmission scheduled by RAR UL grant or by DCI format 0_0 with CRC scrambled by TC-RNTI, sequence hopping is disabled="disabled" and group hopping is enabled or disabled="disabled" by the higher-layer parameter groupHoppingEnabledTransformPrecoding;
- for all other transmissions, sequence hopping and group hopping are enabled or disabled="disabled" by the respective higher-layer parameters sequenceHopping and sequenceGroupHopping if these parameters are provided, otherwise, the same hopping mode as for Msg3 shall be used.
The UE is not expected to handle the case of combined sequence hopping and group hopping.
The quantity \(l\) above is the OFDM symbol number in the slot except for the case of double-symbol DMRS in which case \(l\) is the OFDM symbol number in the slot of the first symbol of the double-symbol DMRS.
6.4.1.1.2 (void) #
6.4.1. 1.3 Precoding and mapping to physical resources #
The sequence \(r(m)\) shall be mapped to the intermediate quantity \({\overset{\sim}{a}}_{k,l}^{({\overset{\sim}{p}}_{j},\mu)}\) according to
- if transform precoding is not enabled,
- if the higher-layer parameter dmrs-TypeEnh is configured
- otherwise
- if transform precoding is enabled
where \(w_{\text{f}}\left( {k'} \right)\), \(w_{\text{t}}\left( {l'} \right)\), and \(\Delta\) are given by Tables 6.4.1.1.3-1 and 6.4.1.1.3-2 and the configuration type is given by the higher-layer parameter DMRS-UplinkConfig, and both \(k'\) and \(\Delta\) correspond to \({\overset{\sim}{p}}_{0},\ldots,{\overset{\sim}{p}}_{\nu - 1}\). The intermediate quantity \({\overset{\sim}{a}}_{k,l}^{{(\overset{\sim}{p}}_{j},\mu)} = 0\) if Δ corresponds to any other antenna ports than\({\overset{\sim}{p}}_{j}\).
The intermediate quantity \({\overset{\sim}{a}}_{k,l}^{({\overset{\sim}{p}}_{j},\mu)}\) shall be precoded, multiplied with the amplitude scaling factor \(\beta_{\text{PUSCH}}^{\text{DMRS}}\) in order to conform to the transmit power specified in [6, TS 38.214], and mapped to physical resources according to
\(\begin{bmatrix} a_{k,l}^{({p_{0},\mu})} \\ \vdots \\ a_{k,l}^{({p_{\rho - 1},\mu})} \end{bmatrix} = \beta_{\text{PUSCH}}^{\text{DMRS}}W\begin{bmatrix} {\overset{\sim}{a}}_{k,l}^{({{\overset{\sim}{p}}_{0},\mu})} \\ \vdots \\ {\overset{\sim}{a}}_{k,l}^{({{\overset{\sim}{p}}_{\upsilon - 1},\mu})} \end{bmatrix}\)
where
- the precoding matrix \(W\) is given by clause 6.3.1.5,
- the set of antenna ports \(\left\{ {p_{0},\ldots,p_{\rho - 1}} \right\}\) is given by clause 6.3.1.5, and
- the set of antenna ports \(\left\{ {{\overset{\sim}{p}}_{0},\ldots,{\overset{\sim}{p}}_{\rho - 1}} \right\}\) is given by [6, TS 38.214];
and the following conditions are fulfilled:
- the resource elements \({\overset{\sim}{a}}_{k,l}^{({\overset{\sim}{p}}_{j},\mu)}\) are within the common resource blocks allocated for PUSCH transmission.
The reference point for \(k\) is
- subcarrier 0 in common resource block 0 if transform precoding is not enabled, and
- subcarrier 0 of the lowest-numbered resource block of the scheduled PUSCH allocation if transform precoding is enabled.
The reference point for \(l\) and the position \(\ell_0\) of the first DM-RS symbol depends on the mapping type:
- for PUSCH mapping type A:
- \(l\) is defined relative to the start of the slot if frequency hopping is disabled="disabled" and relative to the start of each hop in case frequency hopping is enabled
- \(\ell_0\) is given by the higher-layer parameter dmrs-TypeA-Position
- for PUSCH mapping type B:
- \(l\) is defined relative to the start of the scheduled PUSCH resources if frequency hopping is disabled="disabled" and relative to the start of each hop in case frequency hopping is enabled
- \(l_{0} = 0\)
The position(s) of the DM-RS symbols is given by \(\overline{l}\) and duration \(l_{\text{d}}\) where
- \(l_{\text{d}}\) is the duration between the first OFDM symbol of the slot and the last OFDM symbol of the scheduled PUSCH resources in the slot for PUSCH mapping type A according to Tables 6.4.1.1.3-3 and 6.4.1.1.3-4 if intra-slot frequency hopping is not used, or
- \(l_{\text{d}}\) is the duration of scheduled PUSCH resources for PUSCH mapping type B according to Tables 6.4.1.1.3-3 and 6.4.1.1.3-4 if intra-slot frequency hopping is not used, or
- \(l_{\text{d}}\) is the duration per hop according to Table 6.4.1.1.3-6 if intra-slot frequency hopping is used.
- if the higher-layer parameter maxLength in DMRS-UplinkConfig is not configured, or for a msgA transmission msgA-MaxLength in msgA-DMRS-Config is not configured, the tables shall be used according to single-symbol DM-RS
- if the higher-layer parameter maxLength in DMRS-UplinkConfig is equal to 'len2', the associated DCI or configured grant configuration determines whether single-symbol or double-symbol DM-RS shall be used
- if the higher-layer parameter msgA-MaxLength in msgA-DMRS-Config is equal to 'len2', double-symbol DM-RS shall be used
- if the higher-layer parameter dmrs-AdditionalPosition is not set to 'pos0' and intra-slot frequency hopping is enabled according to clause 7.3.1.1.2 in [4, TS 38.212] and by higher layer, Tables 6.4.1.1.3-6 shall be used assuming dmrs-AdditionalPosition is equal to 'pos1' for each hop.
For PUSCH mapping type A,
- the case dmrs-AdditionalPosition is equal to 'pos3' is only supported when dmrs-TypeA-Position is equal to 'pos2';
- \(l_{\text{d}} = 4\) symbols in Table 6.4.1.1.3-4 is only applicable when dmrs-TypeA-Position is equal to 'pos2'.
For msgA transmitted using PUSCH mapping type A,
- the case msgA-DMRS-AdditionalPosition is equal to 'pos3' is only supported when dmrs-TypeA-Position is equal to 'pos2';
- 'dmrs-AdditionalPosition' in Tables 6.4.1.1.3-3 to 6.4.1.1.3-6 shall be replaced by msgA-DMRS-AdditionalPosition;
- only PUSCH DM-RS configuration type 1 is supported;
- only basic DM-RS multiplexing in Table 6.4.1.1.3-5 is supported.
For msgA transmitted using PUSCH mapping type B,
- 'dmrs-AdditionalPosition' in Tables 6.4.1.1.3-3 to 6.4.1.1.3-6 shall be replaced by msgA-DMRS-AdditionalPosition;
- only PUSCH DM-RS configuration type 1 is supported;
- only basic DM-RS multiplexing in Table 6.4.1.1.3-5 is supported.
The time-domain index \(l'\), and the supported antenna ports \({\overset{\sim}{p}}_{j}\) are given by Table 6.4.1.1.3-5.

6.4.1.4.4 Sounding reference signal slot configuration #
Throughout this clause, when the higher layer parameter numberOfHops is provided for SRS-PosResource, the sounding reference signal slot configuration applies to a given hop.
For an SRS resource configured as periodic or semi-persistent by the higher-layer parameter resourceType, a periodicity \(T_{\mathrm{SRS}}\) (in slots) and slot offset \(T_{\text{offset}}\) are configured according to the higher-layer parameter periodicityAndOffset-p or periodicityAndOffset-sp in the SRS-Resource IE, or periodicityAndOffset-p or periodicityAndOffset-sp in the SRS-PosResource IE. Candidate slots in which the configured SRS resource may be used for SRS transmission are the slots satisfying
and, if the higher-layer parameter srs-PosPeriodicConfigHyperSFN-Index is configured for a periodicity larger than or equal to \(2^{\mu} \bullet 10240\) slots, also
where \(N_{\text{SRS}}^{\text{HFN}} \in \left\{ 0,1 \right\}\) is given by the higher-layer parameter srs-PosPeriodicConfigHyperSFN-Index and \(n_{\text{HFN}}\) is the hyper-frame number.
SRS is transmitted as described in clause 6.2.1 of [6, TS 38.214].

A downlink physical channel corresponds to a set of resource elements carrying information originating from higher layers. The following downlink physical channels are defined:
- Physical Downlink Shared Channel, PDSCH
- Physical Broadcast Channel, PBCH
- Physical Downlink Control Channel, PDCCH.
7 .1.2 Overview of physical signals #
A downlink physical signal corresponds to a set of resource elements used by the physical layer but does not carry information originating from higher layers.
The following downlink physical signals are defined:
- Demodulation reference signals, DM-RS
- Phase-tracking reference signals, PT-RS
- Positioning reference signal, PRS
- Channel-state information reference signal, CSI-RS
- Primary synchronization signal, PSS
- Secondary synchronization signal, SSS
- Wake-up signal, WUS
- Low-power synchronization signal, LPSS
7 .2 Physical resources #
The frame structure and physical resources the UE shall assume when receiving downlink transmissions are defined in Clause 4.
The following antenna ports are defined for the downlink:
- Antenna ports starting with 1000 for PDSCH
- Antenna ports starting with 2000 for PDCCH
- Antenna ports starting with 3000 for channel-state information reference signals
- Antenna ports starting with 4000 for SS/PBCH block transmission

The UE shall not assume that two antenna ports are quasi co-located with respect to any QCL type unless specified otherwise.
For DM-RS associated with a PDSCH, the channel over which a PDSCH symbol on one antenna port is conveyed can be inferred from the channel over which a DM-RS symbol on the same antenna port is conveyed only if the two symbols are within the same resource as the scheduled PDSCH, in the same slot, and in the same PRG as described in clause 5.1.2.3 of [6, TS 38.214].
For DM-RS associated with a PDCCH, the channel over which a PDCCH symbol on one antenna port is conveyed can be inferred from the channel over which a DM-RS symbol on the same antenna port is conveyed only if the two symbols are within resources for which the UE may assume the same precoding being used as described in clause 7.3.2.2.
For DM-RS associated with a PBCH, the channel over which a PBCH symbol on one antenna port is conveyed can be inferred from the channel over which a DM-RS symbol on the same antenna port is conveyed only if the two symbols are within a SS/PBCH block transmitted within the same slot, and with the same block index according to clause 7.4.3.1.
7 .3 Physical channels #
7 .3.1 Physical downlink shared channel #
7 .3.1.1 Scrambling #
Up to two codewords \(q \in \{0,1\}\) can be transmitted. In case of single-codeword transmission, \(q=0\).
For each codeword \(q\), the UE shall assume the block of bits \(b^{(q)}(0),\ldots,b^{(q)}\left( M_{\text{bit}}^{(q)} - 1 \right)\), where \(M_{\text{bit}}^{(q)}\) is the number of bits in codeword \(q\) transmitted on the physical channel, are scrambled prior to modulation, resulting in a block of scrambled bits \({\overset{\sim}{b}}^{(q)}(0),\ldots,{\overset{\sim}{b}}^{(q)}\left( M_{\text{bit}}^{(q)} - 1 \right)\)according to
\({\overset{\sim}{b}}^{(q)}(i) = \left( {b^{(q)}(i) + c^{(q)}(i)} \right)\text{mod}2\)
where the scrambling sequence \(c^{(q)}(i)\) is given by clause 5.2.1. The scrambling sequence generator shall be initialized with
where
- \(n_{\mathrm{ID}} \in \{0,1,\ldots,1023\}\) equals the higher-layer parameter dataScramblingIdentityPDSCH if configured and the RNTI equals the C-RNTI, MCS-C-RNTI, or CS-RNTI, and the transmission is not scheduled using DCI format 1_0 in a common search space;

- \(n_{\text{ID}} \in \left\{ {0,1,\ldots,1023} \right\}\) equals the higher-layer parameter dataScramblingIdentityPDSCH in pdsch-ConfigMCCH or pdsch-ConfigMTCH if configured in a common MBS frequency resource for broadcast and the RNTI equals the MCCH-RNTI or G-RNTI, respectively;
- \(n_{\text{ID}} \in \left\{ {0,1,\ldots,1023} \right\}\) equals
- the higher-layer parameter dataScramblingIdentityPDSCH if the codeword is scheduled using a CORESET with CORESETPoolIndex equal to 0;
- the higher-layer parameter dataScramblingIdentityPDSCH2 if the codeword is scheduled using a CORESET with CORESETPoolIndex equal to 1;
if the higher-layer parameters dataScramblingIdentityPDSCH and dataScramblingIdentityPDSCH2 are configured together with the higher-layer parameter CORESETPoolIndex containing two different values, and the RNTI equals the C-RNTI, MCS-C-RNTI, or CS-RNTI, and the transmission is not scheduled using DCI format 1_0 in a common search space;
- \(n_{\text{ID}} = N_{\text{ID}}^{\text{cell}}\) otherwise
and where \(n_{\mathrm{RNTI}}\) corresponds to the RNTI associated with the PDSCH transmission as described in clause 5.1 of [6, TS 38.214].
7 .3.1.2 Modulation #
For each codeword \(q\), the UE shall assume the block of scrambled bits \({\overset{\sim}{b}}^{(q)}(0),\ldots,{\overset{\sim}{b}}^{(q)}\left( M_{\text{bit}}^{(q)} - 1 \right)\) are modulated as described in clause 5.1 using one of the modulation schemes in Table 7.3.1.2-1, resulting in a block of complex-valued modulation symbols \(d^{(q)}(0),\ldots,d^{(q)}\left( M_{\text{symb}}^{(q)} - 1 \right)\).

16QAM | 4 |
64QAM | 6 |
256QAM | 8 |
1024QAM | 10 |
7 .3.1.3 Layer mapping #
The UE shall assume that complex-valued modulation symbols for each of the codewords to be transmitted are mapped onto one or several layers according to Table 7.3.1.3-1. Complex-valued modulation symbols \(d^{(q)}(0),\ldots,d^{(q)}\left( M_{\text{symb}}^{(q)} - 1 \right)\) for codeword \(q\) shall be mapped onto the layers \(x(i) = \begin{bmatrix} {x^{(0)}(i)} & \ldots & {x^{({\upsilon - 1})}(i)} \end{bmatrix}^{\text{T}}\), \(i = 0,1,\ldots,M_{\text{symb}}^{\text{layer}} - 1\) where \(\upsilon\) is the number of layers and \(M_{\text{symb}}^{\text{layer}}\) is the number of modulation symbols per layer.

where \(i = 0,1,\ldots,M_{\text{symb}}^{\text{ap}} - 1\), \(M_{\text{symb}}^{\text{ap}} = M_{\text{symb}}^{\text{layer}}\). The set of antenna ports \(\{p_{0},\ldots,P_{\nu-1}\}\) shall be determined according to the procedure in [4, TS 38.212].
7 .3.1.5 Mapping to virtual resource blocks #
The UE shall, for each of the antenna ports used for transmission of the physical channel, assume the block of complex-valued symbols \(y^{(p)}(0),\ldots,y^{(p)}\left( M_{\text{symb}}^{\text{ap}} - 1 \right)\) conform to the downlink power allocation specified in [6, TS 38.214] and are mapped in sequence starting with \(y^{(p)}(0)\) to resource elements \(\left( {k^{'},l} \right)_{p,\mu}\) in the virtual resource blocks assigned for transmission which meet all of the following criteria:
- they are in the virtual resource blocks assigned for transmission;
- the corresponding physical resource blocks are declared as available for PDSCH according to clause 5.1.4 of [6, TS 38.214];
- the corresponding resource elements in the corresponding physical resource blocks are
- not used for transmission of the associated DM-RS or DM-RS intended for other co-scheduled UEs as described in clause 7.4.1.1.2;
- not used for non-zero-power CSI-RS, which is according to clause 7.4.1.5 and not configured by the TRS-ResourceSet IE, if the corresponding physical resource blocks are for a PDSCH scheduled by a PDCCH with the CRC scrambled by C-RNTI, MCS-C-RNTI, CS-RNTI, G-RNTI for multicast, G-CS-RNTI, or a PDSCH with SPS, except if the non-zero-power CSI-RS is a CSI-RS configured by the higher-layer parameter CSI-RS-Resource-Mobility in the MeasObjectNR IE or except if the non-zero-power CSI-RS is an aperiodic non-zero-power CSI-RS resource;
- not used for PT-RS according to clause 7.4.1.2;
- not declared as 'not available for PDSCH according to clause 5.1.4 of [6, TS 38.214].
The mapping to resource elements \((k',l)_{p,\mu}\) allocated for PDSCH according to [6, TS 38.214] and not reserved for other purposes shall be in increasing order of first the index \(k'\) over the assigned virtual resource blocks, where \(k^{'} = 0\) is the first subcarrier in the lowest-numbered virtual resource block assigned for transmission, and then the index \(l\).
7.3.1.6 Mapping from virtual to physical resource blocks #
The UE shall assume the virtual resource blocks are mapped to physical resource blocks according to the indicated mapping scheme, non-interleaved or interleaved mapping. If no mapping scheme is indicated, the UE shall assume non-interleaved mapping.
For non-interleaved VRB-to-PRB mapping, virtual resource block \(n\) is mapped to physical resource block \(n\), except for PDSCH transmissions scheduled with DCI format 1_0 in a common search space in which case virtual resource block \(n\) is mapped to physical resource block \(n + N_{\text{start}}^{\text{CORESET}}\) where \(N_{\text{start}}^{\text{CORESET}}\) is the lowest-numbered physical resource block in the control resource set where the corresponding DCI was received. When two PDCCH candidates from two linked common search space sets as indicated by the higher-layer parameter searchSpaceLinking are detected, and the two linked common search space sets are associated with different control resource sets, the control resource set with the lowest number among the two linked control resource sets is used to determine \(N_{\text{start}}^{\text{CORESET}}\).
For interleaved VRB-to-PRB mapping, the mapping process is defined by:
- Resource block bundles are defined as

- resource block bundle \(N_{\text{bundle}} - 1\) consists of \(N_{\text{BWP,init}}^{\text{size}}\text{mod}L\) resource blocks if \(N_{\text{BWP,init}}^{\text{size}}\text{mod}L > 0\) and \(L\) resource blocks otherwise,
- all other resource block bundles consists of \(L\) resource blocks.
- for PDSCH transmissions scheduled with DCI format 1_0 in any common search space in bandwidth part \(i\) with starting position \(N_{\text{BWP,}i}^{\text{start}}\), other than Type0-PDCCH common search space in CORESET 0, the set of \(N_{\text{BWP,init}}^{\text{size}}\) virtual resource blocks \(\left\{ {0,1,\ldots,N_{\text{BWP,init}}^{\text{size}} - 1} \right\}\), where \(N_{\text{BWP,init}}^{\text{size}}\) is the size of CORESET 0 if CORESET 0 is configured for the cell and the size of initial downlink bandwidth part if CORESET 0 is not configured for the cell, are divided into \(N_{\text{bundle}}\) virtual resource-block bundles in increasing order of the virtual resource-block number and virtual bundle number and the set of \(N_{\text{BWP,init}}^{\text{size}}\) physical resource blocks \(\left\{ {N_{\text{start}}^{\text{CORESET}},N_{\text{start}}^{\text{CORESET}} + 1,\ldots,N_{\text{start}}^{\text{CORESET}} + N_{\text{BWP,init}}^{\text{size}} - 1} \right\}\) are divided into \(N_{\text{bundle}}\) physical resource-block bundles in increasing order of the physical resource-block number and physical bundle number, where \(N_{\text{bundle}} = \left\lceil {\left( {N_{\text{BWP,init}}^{\text{size}} + \left( {N_{\text{BWP,}i}^{\text{start}} + N}_{\text{start}}^{\text{CORESET}} \right)\text{mod}L} \right)/L} \right\rceil\), \(L = 2\) is the bundle size, and \(N_{\text{start}}^{\text{CORESET}}\) is the lowest-numbered physical resource block in the control resource set where the corresponding DCI was received. When two PDCCH candidates from two linked search space sets as indicated by the higher-layer parameter searchSpaceLinking are detected, and the two linked search space sets are associated with different control resource sets, the control resource set with the lowest number among the two linked control resource sets is used to determine \(N_{\text{start}}^{\text{CORESET}}\).
- resource block bundle 0 consists of \(L - \left( {\left( {N_{\text{BWP,}i}^{\text{start}} + N}_{\text{start}}^{\text{CORESET}} \right)\text{mod}L} \right)\) resource blocks,
- resource block bundle \(N_{\text{bundle}} - 1\) consists of \(\left( {{N_{\text{BWP,init}}^{\text{size}} + N}_{\text{BWP,}i}^{\text{start}} + N}_{\text{start}}^{\text{CORESET}} \right)\text{mod}L\) resource blocks if \(\left( {{N_{\text{BWP,init}}^{\text{size}} + N}_{\text{BWP,}i}^{\text{start}} + N}_{\text{start}}^{\text{CORESET}} \right)\text{mod}L > 0\) and \(L\) resource blocks otherwise,
- all other resource block bundles consists of \(L\) resource blocks.
- for all other PDSCH transmissions, the set of \(N_{\text{BWP},i}^{\text{size}}\) resource blocks in bandwidth part \(i\) with starting position \(N_{\text{BWP,}i}^{\text{start}}\) are divided into \(N_{\text{bundle}} = \left\lceil {\left( {N_{\text{BWP},i}^{\text{size}} + \left( {N_{\text{BWP},i}^{\text{start}}\text{mod}L_{i}} \right)} \right)/L_{i}} \right\rceil\) resource-block bundles in increasing order of the resource-block number and bundle number where \(L_i\) is the bundle size for bandwidth part \(i\) provided by the higher-layer parameter vrb-ToPRB-Interleaver for DCI formats 1_0, 1_1, and 1_3 in a UE-specific search space, or vrb-ToPRB-InterleaverDCI-1-2 for DCI format 1_2, and
- resource block bundle 0 consists of \(L_i - \left(N^{\text{start}}_{\mathrm{BWP},i} \bmod L_i\right)\) resource blocks,
- resource block bundle \(N_{\text{bundle}}-1\) consists of \(\left(N_{\mathrm{BWP},i}^{\mathrm{start}} + N_{\mathrm{BWP},i}^{\mathrm{size}}\right)\bmod L_i\) resource blocks if \(\left(N_{BWP,i}^{\text{start}} + N_{BWP,i}^{\text{size}}\right) \bmod L_i > 0\) and \(L_i\) resource blocks otherwise,
- all other resource block bundles consists of \(L_i\) resource blocks.
- Virtual resource blocks in the interval \(j \in \{0,1,\ldots,N_{\text{bundle}}-1\}\) are mapped to physical resource blocks according to
- virtual resource block bundle \(N_{\text{bundle}}-1\) is mapped to physical resource block bundle \(N_{\text{bundle}}-1\)
- virtual resource block bundle \(j \in \{0,1,\ldots,N_{\text{bundle}}-2\}\) is mapped to physical resource block bundle \(f(j)\) where

- The UE is not expected to be configured with \(L_{i} = 2\) simultaneously with a PRG size of 4 as defined in [6, TS 38.214]
The UE may assume that the same precoding in the frequency domain is used within a PRB bundle and the bundle size is determined by clause 5.1.2.3 in [6, TS 38.214]. The UE shall not make any assumption that the same precoding is used for different bundles of common resource blocks.
For PDSCH transmissions scheduled by DCI format 4_1 or 4_2, and using G-RNTI or G-CS-RNTI, the quantities \(N_{\text{BWP,}i}^{\text{start}}\) and \(N_{\text{BWP},i}^{\text{size}}\) in this clause are replaced by \(N_{\text{MBS,}i}^{\text{start}}\) and \(N_{\text{MBS},i}^{\text{size}}\), respectively, and \(L_{i}\) is the bundle size for the common MBS frequency resource provided by the higher-layer parameter vrb-ToPRB-Interleaver in pdsch-ConfigMulticast.
For PDSCH transmissions scheduled by DCI format 4_0, and using G-RNTI for broadcast, MCCH-RNTI, or Multicast-MCCH-RNTI, the quantities \(N_{\text{BWP,}i}^{\text{start}}\) and \(N_{\text{BWP},i}^{\text{size}}\) in this clause are replaced by \(N_{\text{MBS,}i}^{\text{start}}\) and \(N_{\text{MBS},i}^{\text{size}}\), respectively, and \(L_{i} = 2\).

7.3.2.2 Control-resource set (CORESET) #
A control-resource set consists of \(N_{\text{RB}}^{\text{CORESET}}\) resource blocks in the frequency domain and \(N_{\text{symb}}^{\text{CORESET}} \in \left\{ {1,2,3} \right\}\) symbols in the time domain.
A control-channel element consists of 6 resource-element groups (REGs) where a resource-element group equals one resource block during one OFDM symbol. Resource-element groups within a control-resource set are numbered in increasing order in a time-first manner, starting with 0 for the first OFDM symbol and the lowest-numbered resource block in the control resource set.
A UE can be configured with multiple="multiple" control-resource sets. Each control-resource set is associated with one CCE-to-REG mapping only.
The CCE-to-REG mapping for a control-resource set can be interleaved or non-interleaved and is described by REG bundles:

7.4.1.1.2 Mapping to physical resources #
The UE shall assume the PDSCH DM-RS being mapped to physical resources according to configuration type 1 or configuration type 2 as given by the higher-layer parameter dmrs-Type.
The UE shall assume the sequence \(r(m)\) is scaled by a factor \(\beta_{\text{PDSCH}}^{\text{DMRS}}\) to conform with the transmission power specified in [6, TS 38.214] and mapped to resource elements \(\left( {k,l} \right)_{p,\mu}\) according to
- if the higher-layer parameter dmrs-TypeEnh is configured and the PDSCH is not scheduled by DCI format 1_0, 4_0, or 4_1
- otherwise
where \(w_f(k')\), \(w_t(l')\), and \(\Delta\) are given by Tables 7.4.1.1.2-1 and 7.4.1.1.2-2 and the following conditions are fulfilled:
- the resource elements are within the common resource blocks allocated for PDSCH transmission
The reference point for \(k\) is
- subcarrier 0 of the lowest-numbered resource block in CORESET 0 if the corresponding PDCCH is associated with CORESET 0 and Type0-PDCCH common search space and is addressed to SI-RNTI;
- otherwise, subcarrier 0 in common resource block 0
The reference point for \(l\) and the position \(\ell_0\) of the first DM-RS symbol depends on the mapping type:
- for PDSCH mapping type A:
- \(l\) is defined relative to the start of the slot
- \(l_{0}=3\)if the higher-layer parameter dmrs-TypeA-Position is equal to 'pos3' and \(l_{0}=2\) otherwise
- for PDSCH mapping type B:
- \(l\) is defined relative to the start of the scheduled PDSCH resources
- \(l_{0} = 0\)
The position(s) of the DM-RS symbols is given by \(\overline{l}\) and duration \(l_{\text{d}}\) where
- for PDSCH mapping type A, \(l_{\text{d}}\) is the duration between the first OFDM symbol of the slot and the last OFDM symbol of the scheduled PDSCH resources in the slot
- for PDSCH mapping type B, \(l_{\text{d}}\) is the duration of the scheduled PDSCH resources
and according to Tables 7.4.1.1.2-3 and 7.4.1.1.2-4.
For PDSCH mapping type A
- the case dmrs-AdditionalPosition equals to 'pos3' is only supported when dmrs-TypeA-Position is equal to 'pos2';
- \(l_{\text{d}} = 3\) and \(l_{\text{d}} = 4\) symbols in Tables 7.4.1.1.2-3 and 7.4.1.1.2-4 respectively is only applicable when dmrs-TypeA-Position is equal to 'pos2';
- single-symbol DM-RS, \(l_{1} = 11\) except if all of the following conditions are fulfilled in which case \(l_{1} = 12\):
- the higher-layer parameter lte-CRS-ToMatchAround, lte-CRS-PatternList1, lte-CRS-PatternList2, lte-CRS-PatternList3, or lte-CRS-PatternList4 is configured; and
- the higher-layer parameter dmrs-AdditionalPosition is equal to 'pos1' and \(l_{0} = 3\); and
- the UE has indicated it is capable of additionalDMRS-DL-Alt
For PDSCH mapping type B
- if the PDSCH duration \(l_{\text{d}}\) \(\in \left\{ {2,3,4,5,6,7,8,9,10,11,12,13} \right\}\) OFDM symbols for normal cyclic prefix or \(l_{\text{d}} \in \left\{ {2,4,6} \right\}\) OFDM symbols for extended cyclic prefix, and the front-loaded DM-RS of the PDSCH allocation collides with resources reserved for a search space set associated with a CORESET, \(\overline{l}\) shall be incremented such that the first DM-RS symbol occurs immediately after the CORESET and until no collision with any CORESET occurs, and
- if the PDSCH duration \(l_{\text{d}}\) is 2 symbols, the UE is not expected to receive a DM-RS symbol beyond the second symbol;
- if the PDSCH duration \(l_{d}\) is 5 symbols and if one additional single-symbol DMRS is configured, the UE only expects the additional DM-RS to be transmitted on the 5th symbol when the front-loaded DM-RS symbol is in the 1st symbol of the PDSCH duration, otherwise the UE should expect that the additional DM-RS is not transmitted;
- if the PDSCH duration \(l_{\text{d}}\) is 7 symbols for normal cyclic prefix or 6 symbols for extended cyclic prefix:
- if one additional single-symbol DM-RS is configured, the UE only expects the additional DM-RS to be transmitted on the 5th or 6th symbol when the front-loaded DM-RS symbol is in the 1st or 2nd symbol, respectively, of the PDSCH duration, otherwise the UE should expect that the additional DM-RS is not transmitted;
- if the PDSCH duration \(l_{\text{d}}\) \(\in \left\{ {5,6,7,8,9,10,11,12,13} \right\}\) OFDM symbols, the UE is not expected to receive the front-loaded DM-RS beyond the 4th symbol;
- if the PDSCH duration \(l_{\text{d}}\) is 12 or 13 symbols, the UE is not expected to receive DM-RS mapped to symbol 12 or later in the slot;
- for all values of the PDSCH duration \(l_{\text{d}}\) other than 2, 5, and 7 symbols, the UE is not expected to receive DM-RS beyond the \(\left( l_{\text{d}} - 1 \right)\):th symbol;
- if the PDSCH duration \(l_{\text{d}}\) is less than or equal to 4 OFDM symbols, only single-symbol DM-RS is supported.
- if the higher-layer parameter lte-CRS-ToMatchAround, lte-CRS-PatternList1, lte-CRS-PatternList2, lte-CRS-PatternList3, or lte-CRS-PatternList4 is configured, the PDSCH duration \(l_{\text{d}} = 10\) symbols for normal cyclic prefix, the subcarrier spacing configuration \(\mu = 0\), single-symbol DM-RS is configured, and at least one PDSCH DM-RS symbol in the PDSCH allocation collides with a symbol containing resource elements as indicated by the higher-layer parameter lte-CRS-ToMatchAround, lte-CRS-PatternList1, lte-CRS-PatternList2, lte-CRS-PatternList3, or lte-CRS-PatternList4, then \(\bar{l}\) shall be incremented by one in all slots.
The time-domain index \(l'\) and the supported antenna ports \(p\) are given by Table 7.4.1.1.2-5 where
- single-symbol DM-RS is used if the higher-layer parameter maxLength in the DMRS-DownlinkConfig IE is not configured;
- single-symbol or double-symbol DM-RS is determined by the associated DCI if the higher-layer parameter maxLength in the DMRS-DownlinkConfig IE is equal to 'len2';
- basic or enhanced DM-RS multiplexing is controlled by the higher-layer parameter dmrs-TypeEnh.
In absence of CSI-RS configuration, and unless otherwise configured, the UE may assume PDSCH DM-RS and SS/PBCH block to be quasi co-located with respect to Doppler shift, Doppler spread, average delay, delay spread, and, when applicable, spatial Rx parameters. Unless specified otherwise, the UE may assume that the PDSCH DM-RS within the same CDM group are quasi co-located with respect to Doppler shift, Doppler spread, average delay, delay spread, and spatial Rx (when applicable). The UE may assume that DMRS ports associated with a TCI state as described in clause 5.1.6.2 of [6, TS 38.214] of a PDSCH are QCL with QCL Type A, Type D (when applicable) and average gain.
The UE may assume that no DM-RS collides with the SS/PBCH block.

7.4.1.2 Phase-tracking reference signals for PDSCH #
7 .4.1.2.1 Sequence generation #
The phase-tracking reference signal for subcarrier \(k\) is given by
- If the higher-layer parameter dmrs-TypeEnh is configured
\(r_{k} = r\left( {4m + k'} \right)\)
- otherwise
\(r_{k} = r\left( {2m + k'} \right)\)
where \(r( \bullet )\) is the demodulation reference signal given by clause 7.4.1.1.2 at position \(l_{0}\) and subcarrier \(k\).
7.4.1.2 .2 Mapping to physical resources #
The UE shall assume phase-tracking reference signals being present only in the resource blocks used for the PDSCH, and only if the procedure in [6, TS 38.214] indicates phase-tracking reference signals being used.
If present, the UE shall assume the PDSCH PT-RS is scaled by a factor \(\beta_{\text{PT-RS}}\) to conform with the transmission power specified in clause 4.1 of [6, TS 38.214] and mapped to resource elements \(\left( {k,l} \right)_{p,\mu}\)according to
when all the following conditions are fulfilled
- \(l\) is within the OFDM symbols allocated for the PDSCH transmission
- resource element \(\left( {k,l} \right)_{p,\mu}\) is not used for DM-RS, non-zero-power CSI-RS (except for those configured for mobility measurements or with resourceType in corresponding CSI-ResourceConfig configured as 'aperiodic'), zero-power CSI-RS, SS/PBCH block, a detected PDCCH according to clause 5.1.4.1 of [6, TS38.214], or is declared as 'not available' by clause 5.1.4 of [6, TS 38.214]
The set of time indices \(l\) defined relative to the start of the PDSCH allocation is defined by
1. set \(i = 0\) and \(l_{\text{ref}} = 0\)
2. if any symbol in the interval \(\max\limits_{}{\left( {l_{\text{ref}} + \left( {i - 1} \right)L_{\text{PT-RS}} + 1,l_{\text{ref}}} \right),\ldots,l_{\text{ref}} + iL_{\text{PT-RS}}}\) overlaps with a symbol used for DM-RS according to clause 7.4.1.1.2
- set \(i = 1\)
- set \(l_{\text{ref}}\) to the symbol index of the DM-RS symbol in case of a single-symbol DM-RS and to the symbol index of the second DM-RS symbol in case of a double-symbol DM-RS
- repeat from step 2 as long as \(l_{\text{ref}} + iL_{\text{PT-RS}}\) is inside the PDSCH allocation
3. add \(l_{\text{ref}} + iL_{\text{PT-RS}}\) to the set of time indices for PT-RS
4. increment \(i\) by one
5. repeat from step 2 above as long as \(l_{\text{ref}} + iL_{\text{PT-RS}}\) is inside the PDSCH allocation
where \(L_{\text{PT-RS}} \in \left\{ {1,2,4} \right\}\).
For the purpose of PT-RS mapping, the resource blocks allocated for PDSCH transmission are numbered from 0 to \(N_{RB}-1\) from the lowest scheduled resource block to the highest. The corresponding subcarriers in this set of resource blocks are numbered in increasing order starting from the lowest frequency from 0 to \(N_{sc}^{\mathrm{RB}}\,N_{\mathrm{RB}}-1\). The subcarriers to which the UE shall assume the PT-RS is mapped are given by
\(k = k_{\mathrm{ref}}^{\mathrm{RE}} + \bigl(i K_{\mathrm{PT\!-\!RS}} + k_{\mathrm{ref}}^{\mathrm{RB}}\bigr) N_{\mathrm{sc}}^{\mathrm{RB}} k_{\mathrm{ref}}^{\mathrm{RB}} = \begin{cases} n_{\mathrm{RNTI}} \bmod K_{\mathrm{PT\!-\!RS}}, & \text{if } N_{\mathrm{RB}} \bmod K_{\mathrm{PT\!-\!RS}} = 0, \\ n_{\mathrm{RNTI}} \bmod \bigl(N_{\mathrm{RB}} \bmod K_{\mathrm{PT\!-\!RS}}\bigr), & \text{otherwise} \end{cases}\)
where
- \(i = 0,1,2,\ldots\)
- \(k_{\mathrm{ref}}^{\mathrm{RE}}\) is given by Table 7.4.1.2.2-1 for the DM-RS port associated with the PT-RS port according to clause 5.1.6.3 in [6, TS 38.214]. If the higher-layer parameter resourceElementOffset in the PTRS-DownlinkConfig IE is not configured, the column corresponding to 'offset00' shall be used.
- \(n_{\mathrm{RNTI}}\) is the RNTI associated with the DCI scheduling the transmission
- \(N_{RB}\) is the number of resource blocks scheduled
- \(K_{\text{PT-RS}} \in \left\{ 2,4 \right\}\) is given by [6, TS 38.214].

7 .4.1.3 Demodulation reference signals for PDCCH #
7.4.1.3.1 Sequence generation #
The UE shall assume the reference-signal sequence \(r_{l}(m)\) for OFDM symbol \(l\) is defined by
\(r_{l}(m)=\frac{1}{\sqrt{2}}\left(1-2\cdot c(2m)\right)+j\,\frac{1}{\sqrt{2}}\left(1-2\cdot c(2m+1)\right)\).
where the pseudo-random sequence \(c(i)\) is defined in clause 5.2.1. The pseudo-random sequence generator shall be initialized with
\(c_{\text{init}} = \left( {2^{17}\left( {N_{\text{symb}}^{\text{slot}}n_{\text{s,f}}^{\mu} + l + 1} \right)\left( {2N_{\text{ID}} + 1} \right) + {2N}_{\text{ID}}} \right)\text{mod}2^{31}\)
where \(l\) is the OFDM symbol number within the slot, \(n_{\text{s,f}}^{\mu}\) is the slot number within a frame, and
- \(N_{\text{ID}} \in \left\{ {0,1,\ldots,65535} \right\}\) is given by the higher-layer parameter pdcch-DMRS-ScramblingID if provided;
- \(N_{\text{ID}} \in \left\{ {0,1,\ldots,65535} \right\}\) is given by the higher-layer parameter pdcch-DMRS-ScramblingID if configured for a common search space in a common MBS frequency resource;
- \(N_{\text{ID}} = N_{\text{ID}}^{\text{cell}}\) otherwise.
7.4.1.3.2 Mapping to physical resources #
The UE shall assume the sequence \(r_{l}(m)\) is mapped to resource elements \(\left( {k,l} \right)_{p,\mu}\) according to
\(\begin{aligned} a_{k,l}^{(p,\mu)} &= \beta_{\mathrm{DMRS}}^{\mathrm{PDCCH}} \cdot r_l(3n + k') \\ k &= n N_{sc}^{\mathrm{RB}} + 4k' + 1 \\ k' &= 0,1,2 \\ n &= 0,1,\ldots \end{aligned}\)
where the following conditions are fulfilled
- they are within the resource element groups constituting the PDCCH the UE attempts to decode if the higher-layer parameter precoderGranularity equals sameAsREG-bundle,
- all resource-element groups within the set of contiguous resource blocks in the CORESET where the UE attempts to decode the PDCCH if the higher-layer parameter precoderGranularity equals allContiguousRBs.
The reference point for \(k\) is
- subcarrier 0 of the lowest-numbered resource block in the CORESET if the CORESET is configured by the PBCH or by the controlResourceSetZero field in the PDCCH-ConfigCommon IE,
- subcarrier 0 in common resource block 0 otherwise
The quantity \(l\) is the OFDM symbol number within the slot.
The antenna port \(p = 2000\).
A UE not attempting to detect a PDCCH in a CORESET shall not make any assumptions on the presence or absence of DM-RS in the CORESET.
In absence of CSI-RS configuration, and unless otherwise configured, the UE may assume PDCCH DM-RS and SS/PBCH block to be quasi co-located with respect to Doppler shift, Doppler spread, average delay, delay spread, and, when applicable, spatial Rx parameters.
7 .4.1.4 Demodulation reference signals for PBCH #
7.4.1.4.1 Sequence generation #
The UE shall assume the reference-signal sequence \(r(m)\) for an SS/PBCH block is defined by
\(r(m)=\frac{1}{\sqrt{2}}\left(1-2\cdot c(2m)\right)+j\frac{1}{\sqrt{2}}\left(1-2\cdot c(2m+1)\right)\)
where \(c(n)\) is given by clause 5.2. The scrambling sequence generator shall be initialized at the start of each SS/PBCH block occasion with
\(c_{\mathrm{init}} = 2^{11}(\bar{i}_{\mathrm{SSB}}+1)\left(\left\lfloor \frac{N_{\mathrm{ID}}^{\mathrm{cell}}}{4} \right\rfloor + 1\right) + 2^{6}(\bar{i}_{\mathrm{SSB}}+1) + \left(N_{\mathrm{ID}}^{\mathrm{cell}} \bmod 4\right)\)
where
- for \({\bar{L}}_{\max} = 4\), \(\overline{i}_{\mathrm{SSB}} = i_{\mathrm{SSB}} + 4 n_{\mathrm{hf}}\) where \(n_{hf}\) is the number of the half-frame in which the PBCH is transmitted in a frame with \(n_{bf}=0\) for the first half-frame in the frame and \(n_{hf}=1\) for the second half-frame in the frame, and \(i_{SSB}\) is the two least significant bits of the candidate SS/PBCH block index as defined in [5, TS 38.213]
- for \({\bar{L}}_{\max} > 4\), \(\overline{i}_{\mathrm{SSB}}=i_{\mathrm{SSB}}\) where \(i_{SSB}\) is the three least significant bits of the candidate SS/PBCH block index as defined in [5, TS 38.213]
with \({\bar{L}}_{\max}\) being the maximum number of candidate SS/PBCH blocks in a half frame, as described in [5, TS 38.213].
7.4.1.4.2 Mapping to physical resources #
Mapping to physical resources is described in clause 7.4.3.
7 .4.1.5 CSI reference signals #
7.4.1.5.1 General #
Zero-power (ZP) and non-zero-power (NZP) CSI-RS are defined
- for a non-zero-power CSI-RS configured by the NZP-CSI-RS-Resource IE or by the CSI-RS-Resource-Mobility field in the CSI-RS-ResourceConfigMobility IE or by the TRS-ResourceSet IE, the sequence shall be generated according to clause 7.4.1.5.2 and mapped to resource elements according to clause 7.4.1.5.3
- for a zero-power CSI-RS configured by the ZP-CSI-RS-Resource IE, the UE shall assume that the resource elements defined in clause 7.4.1.5.3 are not used for PDSCH transmission subject to clause 5.1.4.2 of [6, TS 38.214]. The UE performs the same measurement/reception on channels/signals except PDSCH regardless of whether they collide with ZP CSI-RS or not.
7.4.1.5. 2 Sequence generation #
The UE shall assume the reference-signal sequence \(r(m)\) is defined by
\(r(m)=\frac{1}{\sqrt{2}}\left(1-2\cdot c(2m)\right)+j\frac{1}{\sqrt{2}}\left(1-2\cdot c(2m+1)\right)\)
where the pseudo-random sequence \(c(i)\) is defined in clause 5.2.1. The pseudo-random sequence generator shall be initialised with
at the start of each OFDM symbol where \(n_{\text{s,f}}^{\mu}\) is the slot number within a radio frame, \(l\) is the OFDM symbol number within a slot, and \(n_{\mathrm{ID}}\) equals the higher-layer parameter scramblingID or sequenceGenerationConfig.
7.4.1.5. 3 Mapping to physical resources #
For each CSI-RS configured, the UE shall assume the sequence \(r(m)\) being mapped to resources elements \(\left( {k,l} \right)_{p,\mu}\) according to
when the following conditions are fulfilled:
- the resource element \(\left( {k,l} \right)_{p,\mu}\) is within the resource blocks occupied by the CSI-RS resource for which the UE is configured
The reference point for \(k = 0\) is subcarrier 0 in common resource block 0.
The value of \(\rho\) is given by the higher-layer parameter density in the CSI-RS-ResourceMapping IE or the CSI-RS-CellMobility IE.
The number of ports \(N\) per CSI-RS resource is given by the higher-layer parameter nrofPorts and the number of CSI-RS resources by the total number of CSI-RS ports \(N_{\text{tot}}\)
- if \(N_{\text{tot}} \in \left\{ {1,2,4,8,12,16,24,32} \right\}\), there is one CSI-RS resource with \(N\) CSI-RS ports, \(q = 0\), and \(N_{\text{tot}} = N\);
- if \(N_{\text{tot}} \in \left\{ {48,64,128} \right\}\), the aggregated resource for the \(N_{\text{tot}} = KN\) ports is formed by aggregating \(K\) CSI-RS resources with \(N\) CSI-RS ports each, where the possible combinations of \(N_{\text{tot}}\), \(K\), and \(N\) are given by Table 7.4.1.5.3-6, and where \(q = 0,\ldots,K - 1\) is the CSI-RS resource index within the aggregated CSI-RS resource.
For NZP CSI-RS configured by the TRS-ResourceSet IE, the density \(\rho = 3\) and number of ports \(X = 1\).
The UE is not expected to receive CSI-RS and DM-RS on the same resource elements.
The UE shall assume \(\beta_{\mathrm{CSIRS}}>0\) for a non-zero-power CSI-RS where \(\beta_{\mathrm{CSIRS}}\) is selected="selected" such that the power offset specified by the higher-layer parameter powerControlOffsetSS in the NZP-CSI-RS-Resource IE or in the TRS-ResourceSet IE, if provided, is fulfilled.
The quantities \(k_{q}'\), \(l_{q}'\), \(w_{\text{f}}\left( k_{q}' \right)\), and \(w_{\text{t}}\left( l_{q}' \right)\) are given by Tables 7.4.1.5.3-1 to 7.4.1.5.3-5 where each \(\left( {{\bar{k}}_{q},{\bar{l}}_{q}} \right)\) in a given row of Table 7.4.1.5.3-1 corresponds to a CDM group of size 1 (no CDM) or size 2, 4, or 8. The CDM type is provided by the higher layer parameter cdm-Type in the CSI-RS-ResourceMapping IE. For NZP CSI-RS configured by the TRS-ResourceSet IE, the CDM type is 'noCDM'. The indices \(k_{i}'\) and \(l_{i}'\) index resource elements within a CDM group.
The time-domain locations \(l_{0} \in \left\{ {0,1,\ldots,13} \right\}\) and \(l_{1} \in \left\{ {2,3,\ldots,12} \right\}\) are provided by the higher-layer parameters firstOFDMSymbolInTimeDomain and firstOFDMSymbolInTimeDomain2, respectively, in the CSI-RS-ResourceMapping IE or the CSI-RS-ResourceConfigMobility IE and defined relative to the start of a slot. For NZP CSI-RS configured by TRS-ResourceSet IE, the time-domain location \(l_{0} \in \left\{ {0,1,\ldots,13} \right\}\) is provided by the higher-layer parameter firstOFDMSymbolInTimeDomain or firstOFDMSymbolInTimeDomain+4.
The frequency-domain location is given by a bitmap provided by the higher-layer parameter frequencyDomainAllocation in the CSI-RS-ResourceMapping IE, the CSI-RS-ResourceConfigMobility IE, or the TRS-ResourceSet IE, with the bitmap and value of \(k_{i}\) in Table 7.4.1.5.3-1 given by
- \(\left[ b_{3} \cdots b_{0} \right]\), \(k_{i - 1} = f(i)\) for row 1 of Table 7.4.1.5.3-1
- \(\left[ b_{11} \cdots b_{0} \right]\), \(k_{i - 1} = f(i)\) for row 2 of Table 7.4.1.5.3-1
- \(\left[b_{2}\cdots b_{0}\right]\), \(k_{i - 1} = 4f(i)\) for row 4 of Table 7.4.1.5.3-1
- \( [b_{5}\cdots b_{0}] \), \(k_{i - 1} = 2f(i)\) for all other cases
where \(f(i)\) is the bit number of the \(i^{\text{th}}\) bit in the bitmap set to one, repeated across every \(\left\lceil {1/\rho} \right\rceil\) of the resource blocks configured for CSI-RS reception by the UE. The starting position and number of the resource blocks in which the UE shall assume that CSI-RS is transmitted are given by the higher-layer parameters freqBand and density in the CSI-RS-ResourceMapping IE for the bandwidth part given by the higher-layer parameter BWP-Id in the CSI-ResourceConfig IE or given by the higher-layer parameters nrofPRBs in the CSI-RS-CellMobility IE where the the startPRB given by csi-rs-MeasurementBW is relative to common resource block 0. For NZP CSI-RS configured by TRS-ResourceSet IE, the starting position and number of the resource blocks in which the CSI-RS can be transmitted are given by the higher-layer parameters nrofRBs, and startingRB in the TRS-ResourceSet IE, where startingRB is relative to common resource block 0 and the density \(\rho = 3\).
The UE shall assume that a CSI-RS is transmitted using antenna ports \(p\) numbered according to
\(p = 3000 + p'\)
where
- if the number of CSI-RS ports \(N_{\text{tot}} \in \left\{ {1,2,4,8,12,16,24,32} \right\}\)

For a CSI-RS resource configured as periodic or semi-persistent by the higher-layer parameter resourceType, configured by the higher-layer parameter CSI-RS-CellMobility, or configured by the higher-layer parameter TRS-ResourceSet, the UE shall assume that the CSI-RS is transmitted in slots satisfying
where the periodicity \(T_{\text{CSI-RS}}\) (in slots) and slot offset \(T_{\text{offset}}\) are obtained from the higher-layer parameter CSI-ResourcePeriodicityAndOffset, slotConfig, periodicityAndOffset. The UE shall assume that CSI-RS is transmitted in a candidate slot as described in clause 11.1 of [5, TS 38.213], clause 10.4B of [5, TS 38.213].
The UE may assume that antenna ports within a CSI-RS resource are quasi co-located with QCL Type A, Type D (when applicable), and average gain.

7.4.2. 3.2 Mapping to physical resources #
Mapping to physical resources is described in clause 7.4.3.
7.4.3 SS/PBCH block #
7.4.3.1 Time-frequency structure of an SS/PBCH block #
In the time domain, an SS/PBCH block consists of 4 OFDM symbols, numbered in increasing order from 0 to 3 within the SS/PBCH block, where PSS, SSS, and PBCH with associated DM-RS are mapped to symbols as given by Table 7.4.3.1-1.
In the frequency domain, an SS/PBCH block consists of 240 contiguous subcarriers with the subcarriers numbered in increasing order from 0 to 239 within the SS/PBCH block. The quantities \(k\) and \(l\) represent the frequency and time indices, respectively, within one SS/PBCH block. The UE may assume that the complex-valued symbols corresponding to resource elements denoted as 'Set to 0' in Table 7.4.3.1-1 are set to zero. The quantity \(v\) in Table 7.4.3.1-1 is given by \(v = N_{\text{ID}}^{\text{cell}}\text{mod}4\). The quantity \(k_{\text{SSB}}\) is the subcarrier offset from subcarrier 0 in common resource block \(N_{\text{CRB}}^{\text{SSB}}\) to the lowest-numbered subcarrier of the SS/PBCH block, or the SS/PBCH block after puncturing if applicable, where \(N_{\text{CRB}}^{\text{SSB}}\) is obtained from the higher-layer parameter offsetToPointA.
- For operation with shared spectrum channel access in FR2-2 and for operation without shared spectrum channel access, the 4 least significant bits of \(k_{\text{SSB}}\) are given by the higher-layer parameter ssb-SubcarrierOffset and for FR1 the most significant bit of \(k_{\text{SSB}}\) is given by \({\bar{a}}_{\bar{A} + 5}\) in the PBCH payload as defined in clause 7.1.1 of [4, TS 38.212].
- For operation with shared spectrum channel access in FR1, the 4 least significant bits of \({\bar{k}}_{\text{SSB}}\) are given by the higher-layer parameter ssb-SubcarrierOffset and the most significant bit of \({\bar{k}}_{\text{SSB}}\) is given by \({\bar{a}}_{\bar{A} + 5}\) in the PBCH payload as defined in clause 7.1.1 of [4, TS 38.212]. If \({\bar{k}}_{\text{SSB}} \geq 24\), \(k_{\text{SSB}} = {\bar{k}}_{\text{SSB}}\) ; otherwise, \(k_{\text{SSB}} = 2\left\lfloor {{\bar{k}}_{\text{SSB}}/2} \right\rfloor\).
If ssb-SubcarrierOffset is not provided, \(k_{\text{SSB}}\) is derived from the frequency difference between the SS/PBCH block and Point A.
The UE may assume that the complex-valued symbols corresponding to resource elements that are part of a common resource block partially or fully overlapping with an SS/PBCH block, or an SS/PBCH block after puncturing if applicable, and not used for SS/PBCH transmission are set to zero in the OFDM symbols partially or fully overlapping with OFDM symbols where SS/PBCH is transmitted.
For an SS/PBCH block, the UE shall assume
- antenna port \(p = 4000\) is used for transmission of PSS, SSS, PBCH and DM-RS for PBCH,
- the same cyclic prefix length and subcarrier spacing for the PSS, SSS, PBCH and DM-RS for PBCH,
- for SS/PBCH block type A, \(\mu \in \left\{ 0,1 \right\}\) and \(k_{\text{SSB}} \in \left\{ {0,1,2,\ldots,23} \right\}\) with the quantities \(k_{\text{SSB}}\), and \(N_{\text{CRB}}^{\text{SSB}}\) expressed in terms of 15 kHz subcarrier spacing, and
- for SS/PBCH block type B in FR2-1 and FR2-NTN, \(\mu \in \left\{ 3,4 \right\}\) and \(k_{\text{SSB}} \in \left\{ {0,1,2,\ldots,11} \right\}\) with the quantity \(k_{\text{SSB}}\) expressed in terms of the subcarrier spacing provided by the higher-layer parameter subCarrierSpacingCommon and \(N_{\text{CRB}}^{\text{SSB}}\) expressed in terms of 60 kHz subcarrier spacing;
- for SS/PBCH block type B in FR2-2, \(\mu \in \left\{ {3,5,6} \right\}\) and \(k_{\text{SSB}} \in \left\{ {0,1,2,\ldots,11} \right\}\) with the quantity \(k_{\text{SSB}}\) expressed in terms of the SS/PBCH block subcarrier spacing and \(N_{\text{CRB}}^{\text{SSB}}\) expressed in terms of 60 kHz subcarrier spacing;
- the centre of subcarrier 0 of resource block \(N_{\text{CRB}}^{\text{SSB}}\) coincides with the centre of subcarrier 0 of a common resource block with the subcarrier spacing
- provided by the higher-layer parameter subCarrierSpacingCommon for operation without shared spectrum channel access in FR1, FR2-1 and FR2-NTN; and
- same as the subcarrier spacing of the SS/PBCH block for operation without shared spectrum access in FR2-2 and for operation with shared spectrum channel access.
- This common resource block overlaps with subcarrier 0 of the lowest-numbered resource block of the SS/PBCH block, or the SS/PBCH block after puncturing if applicable.
The UE may assume that SS/PBCH blocks transmitted with the same block index on the same center frequency location are quasi co-located with respect to Doppler spread, Doppler shift, average gain, average delay, delay spread, and, when applicable, spatial Rx parameters. The UE shall not assume quasi co-location for any other SS/PBCH block transmissions other than what is specified in [5, TS 38.213].
For cell search on a carrier with a channel bandwidth of 3 MHz, the UE is not expected to receive subcarriers 0 to 47 and 192 to 239 in any of the 4 OFDM symbols of the SS/PBCH block, where the remaining 12 resource blocks form the SS/PBCH block after puncturing.

- Sidelink positioning reference signal, SL PRS
8 .2 Physical resources #
8.2.1 General #
In a shared SL PRS resource pool, the OFDM symbol immediately preceding the symbols which are configured for use by PSFCH if PSFCH is configured in this slot, and the last symbol configured for sidelink in a slot, serve as guard symbol(s). In a dedicated SL PRS resource pool, the last symbol configured for sidelink in a slot serves as a guard symbol.

Values in the range 0 – 3299 represent the number of the DC subcarrier, the value 3300 indicates that the DC subcarrier is located outside the resource grid, and the value 3301 indicates that the position of the DC subcarrier in the sidelink is undetermined. The DC subcarrier location offset relative to the center of the indicated subcarrier is given by \(7.5 + 5N\text{kHz}\) if frequencyShift7p5khzSL is provided and by \(5N\text{kHz}\) otherwise, where \(N \in \left\{ {- 1,0,1} \right\}\) is given by the higher-layer parameter valueN.

For sidelink transmissions:
If the UE has a serving cell fulfilling the S criterion according to clause 8.2 of [13, TS 38.304]

Otherwise
- The timing of reference radio frame i and \(N_{TA,\text{offset}}\) value are given by clause 12.2.2, 12.2.3, 12.2.4 or 12.2.5 of [12, TS 38.133].
